text: Promising cathode materials for fluoride-ion batteries (FIBs) are 3d transition
metal containing oxides with Ruddlesden-Popper-type structure. So far, multi-elemental
compositions were not investigated, but could alternate electrochemical performance
similar to what has been found for cathode materials for lithium-ion batteries.
Within this study, we investigate RP type La2Ni0.75Co0.25O4.08 as an intercalation-based
active cathode material for all-solid-state FIBs. We determine the structural
changes of La2Ni0.75Co0.25O4.08 during fluoride intercalation / de-intercalation
by ex-situ X-ray diffraction, which showed that F- insertion leads to transformation
of the parent phase to three different phases. Changes in Ni and Co oxidation
states and coordination environment were examined by X-ray absorption spectroscopy
and magnetic measurements in order to understand the complex reaction behaviour
of the phases in detail, showing that the two transition metals behave differently
in the charging and discharging process. Under optimized operating conditions,
a cycle life of 120 cycles at a critical cut-off capacity of 40 mAh g-1 against
Pb/PbF2 was obtained, which is one of the highest observed for intercalation electrode
materials in FIBs so far. The average Coulombic efficiencies ranged from 85% to
90%. Thus, La2Ni0.75Co0.25O4.08 could be a promising candidate for cycling-stable
high-energy cathode materials for all-solid-state FIBs

text: Room temperature sodium-sulfur (RT Na-S) batteries are considered potential
candidates for stationary power storage applications due to their low cost, broad
active material availability and low toxicity. Challenges, such as high volume
expansion of the S-cathode upon discharge, low electronic conductivity of S as
active material and herewith limited rate capability as well as the shuttling
of polysulfides (PSs) as intermediates often impede the cycle stability and practical
application of Na-S batteries. Sulfurized poly(acrylonitrile) (SPAN) inherently
inhibits the shuttling of PSs and shows compatibility with carbonate-based electrolytes,
however, its exact redox mechanism remained unclear to date. Herein, we implement
a commercially available and simple electrolyte into the Na-SPAN cell chemistry
and demonstrate its high rate and cycle stability. Through the application of
in situ techniques utilizing electronic impedance spectroscopy (EIS) and X-ray
absorption spectroscopy (XAS) at different depths of charge and discharge, an
insight into SPAN’s redox chemistry is obtained.

text: Effective photoinduced charge transfer makes molecular bimetallic assemblies
attractive for applications as active light induced proton reduction systems.
For a more sustainable future, development of competitive base metal dyads is
mandatory. However, the electron transfer mechanisms from the photosensitizer
to the proton reduction catalyst in base metal dyads remain so far unexplored.
We study a Fe-Co dyad that exhibits photocatalytic H2 production activity using
femtosecond X-ray emission spectroscopy, complemented by ultrafast optical spectroscopy
and theoretical time-dependent DFT calculations, to understand the electronic
and structural dynamics after photoexcitation and during the subsequent charge
transfer process from the FeII photosensitizer to the cobaloxime catalyst. Using
this novel approach, the simultaneous measurement of the transient Kalpha X-ray
emission at the iron and cobalt K-edges in a two-colour experiment is enabled
making it possible to correlate the excited state dynamics to the electron transfer
processes. The methodology, therefore, provides a clear and direct spectroscopic
evidence of the Fe->Co electron transfer responsible for the proton reduction
activity.

text: AbstractA new approach for the characterization
of CO2 methanation catalysts prepared by thermal decomposition
of a nickel MOF by hard X‐ray photon‐in/photon‐out spectroscopy in form of high
energy resolution fluorescence detected X‐ray absorption near edge structure spectroscopy
(HERFD‐XANES) and valence‐to‐core X‐ray emission (VtC‐XES) is presented. In contrast
to conventional X‐ray absorption spectroscopy, the increased resolution of both
methods allows a more precise phase determination of the final catalyst, which
is influenced by the conditions during MOF decomposition.

text: The use of iron as a replacement for noble metals in photochemical
and photophysical applications is challenging due to the typically fast deactivation
of short-lived catalytically active states. Recent success of a cyclometalated
iron(III) complex utilizing a bis-tridentate ligand motif inspired the use of
phenyl-1H-pyrazole as a bidentate ligand. Five complexes using the tris(1-phenylpyrazolato-N,C2)iron(III)
complex scaffold are presented. In addition to the parent complex, four derivatives
with functionalization in the meta-position of the phenyl ring are thoroughly
investigated by single crystal diffractometry, UV-Vis-spectroscopy, and cyclic
voltammetry. Advanced X-ray spectroscopy in the form of X-ray absorption and emission
spectroscopy allows unique insights into the electronic structure as well as DFT
calculations. The ligand design leads to overlapping MLCT and LMCT absorption
bands, and emissive behavior is suppressed by low-lying MC states.

text: Photoactive chromium(III) complexes saw a conceptual breakthrough with the
discovery of the prototypical molecular ruby mer-[Cr(ddpd)2]3+ (ddpd = N,N′-dimethyl-N,N′-dipyridin-2-ylpyridine-2,6-diamine),
which shows intense long-lived near-infrared (NIR) phosphorescence from metal-centered
spin-flip states. In contrast to the numerous studies on chromium(III) photophysics,
only 10 luminescent molybdenum(III) complexes have been reported so far. Here,
we present the synthesis and characterization of mer-MoX3(ddpd) (1, X = Cl; 2,
X = Br) and cisfac-[Mo(ddpd)2]3+ (cisfac-[3]3+), an isomeric heavy homologue of
the prototypical molecular ruby. For cisfac-[3]3+, we found strong zero-field
splitting using magnetic susceptibility measurements and electron paramagnetic
resonance spectroscopy. Electronic spectra covering the spin-forbidden transitions
show that the spin-flip states in mer-1, mer-2, and cisfac-[3]3+ are much lower
in energy than those in comparable chromium(III) compounds. While all three complexes
show weak spin-flip phosphorescence in NIR-II, the emission of cisfac-[3]3+ peaking
at 1550 nm is particularly low in energy. Femtosecond transient absorption spectroscopy
reveals a short excited-state lifetime of 1.4 ns, 6 orders of magnitude shorter
than that of mer-[Cr(ddpd)2]3+. Using density functional theory and ab initio
multireference calculations, we break down the reasons for this disparity and
derive principles for the design of future stable photoactive molybdenum(III)
complexes.

text: Macrocyclization reactions are still challenging due to competing oligomerization,
which requires the use of small substrate concentrations. Here, the cationic tungsten
imido and tungsten oxo alkylidene N-heterocyclic carbene complexes [[W(N-2,6-Cl2-C6H3)(CHCMe2Ph(OC6F5)(pivalonitrile)(IMes)+
B(ArF)4−] (W1) and [W(O)(CHCMe2Ph(OCMe(CF3)2)(IMes)(CH3CN)+ B(ArF)4−] (W2) (IMes=1,3-dimesitylimidazol-2-ylidene;
B(ArF)4−=tetrakis(3,5-bis(trifluoromethyl)phenyl borate) have been immobilized
inside the pores of ordered mesoporous silica (OMS) with pore diameters of 3.3
and 6.8 nm, respectively, using a pore-selective immobilization protocol. X-ray
absorption spectroscopy of W1@OMS showed that even though the catalyst structure
is contracted due to confinement by the mesopores, both the oxidation state and
structure of the catalyst stayed intact upon immobilization. Catalytic testing
with four differently sized α,ω-dienes revealed a dramatically increased macrocyclization
(MC) and Z-selectivity of the supported catalysts compared to the homogenous progenitors,
allowing high substrate concentrations of 25 mM. With the supported complexes,
a maximum increase in MC-selectivity from 27 to 81 % and in Z-selectivity from
17 to 34 % was achieved. In general, smaller mesopores exhibited a stronger confinement
effect. A comparison of the two supported tungsten-based catalysts showed that
W1@OMS possesses a higher MC-selectivity, while W2@OMS exhibits a higher Z-selectivity
which can be rationalized by the structures of the catalysts.

text: The effects of backbone amine functionalization in three new homoleptic
C^N^C type ruthenium(II) complexes bearing a tridentate bis‐imidazole‐2‐ylidene
pyridine ligand framework are characterized and studied by single crystal diffraction,
electrochemistry, optical spectroscopy and transient absorption spectroscopy in
combination with ab initio DFT calculations. Functionalization by dimethylamine
groups in 4‐position of the pyridine backbone significantly influences the properties
of the complexes as revealed by comparison with the unfunctionalized references.
As a result of the amine functionalization, a higher molar absorption coefficient
of the MLCT bands, a decreased photoluminescence quantum yield at room temperature
together with a shortened excited state lifetime but an improved photostability
is observed. Introduction of electron donating and withdrawing groups at the NHC
unit modifies the electronic and optical properties, such as the oxidation potential,
absorption and emission properties, and the lifetimes of the excited states.

text: Increasing the metal-to-ligand charge transfer (MLCT) excited state lifetime
of polypyridine iron(II) complexes can be achieved by lowering the ligand's π*
orbital energy and by increasing the ligand field splitting. In the homo- and
heteroleptic complexes [Fe(cpmp)2]2+ (12+) and [Fe(cpmp)(ddpd)]2+ (22+) with the
tridentate ligands 6,2’’-carboxypyridyl-2,2’-methylamine-pyridyl-pyridine (cpmp)
and N,N’-dimethyl-N,N’-di-pyridin-2-ylpyridine-2,6-diamine (ddpd) two or one dipyridyl
ketone moieties provide low energy π* acceptor orbitals. A good metal-ligand orbital
overlap to increase the ligand field splitting is achieved by optimizing the octahedricity
through CO and NMe units between the coordinating pyridines which enable the formation
of six-membered chelate rings. The push-pull ligand cpmp provides intra-ligand
and ligand-to-ligand charge transfer (ILCT, LL'CT) excited states in addition
to MLCT excited states. Ground and excited state properties of 12+ and 22+ were
accessed by X-ray diffraction analyses, resonance Raman spectroscopy, (spectro)electrochemistry,
EPR spectroscopy, X-ray emission spectroscopy, static and time-resolved IR and
UV/Vis/NIR absorption spectroscopy as well as quantum chemical calculations.

text: A two-step seeded-growth method was refined to synthesize Au@Pd core@shell
nanoparticles with thin Pd shells, which were then deposited onto alumina to obtain
a supported Au@Pd/Al2O3 catalyst active for prototypical CO oxidation. By the
strict control of temperature and Pd/Au molar ratio and the use of l-ascorbic
acid for making both Au cores and Pd shells, a 1.5 nm Pd layer is formed around
the Au core, as evidenced by transmission electron microscopy and energy-dispersive
spectroscopy. The core@shell structure and the Pd shell remain intact upon deposition
onto alumina and after being used for CO oxidation, as revealed by additional
X-ray diffraction and X-ray photoemission spectroscopy before and after the reaction.
The Pd shell surface was characterized with in situ infrared (IR) spectroscopy
using CO as a chemical probe during CO adsorption–desorption. The IR bands for
CO ad-species on the Pd shell suggest that the shell exposes mostly low-index
surfaces, likely Pd(111) as the majority facet. Generally, the IR bands are blue-shifted
as compared to conventional Pd/alumina catalysts, which may be due to the different
support materials for Pd, Au versus Al2O3, and/or less strain of the Pd shell.
Frequencies obtained from density functional calculations suggest the latter to
be significant. Further, the catalytic CO oxidation ignition-extinction processes
were followed by in situ IR, which shows the common CO poisoning and kinetic behavior
associated with competitive adsorption of CO and O2 that is typically observed
for noble metal catalysts.

text: Currently, chemistry and physics are strongly dependent on the concept of
the oxidation state. While the formal oxidation state is easily evaluated, the
real physical oxidation state value is often difficult to determine and significantly
varies from the formal values. Determination of the ionization threshold in X-ray
absorption spectroscopy (XANES) relies on the absorption edge position and sometimes
poses limitations, mainly due to the edge resonances. Moreover, the lower energy
states can be probed only within x-soft or XUV photons providing only surface
state information of probed materials. Here, we employ high energy resolution
off-resonant spectroscopy to determine both 1s and 3p binding energies of Fe-based
materials and therefore correlate to their physical oxidation state. The results
are compared to the ones obtained with classical X-ray absorption, X-ray emission,
and photoelectron spectroscopies. The observed differences in binding energies
are discussed in a frame of initial and final state interactions with the atom's
electronic configurations. The presented methodology is discussed towards potential
use to single-shot experiments and application at X-ray free-electron lasers.
Alternatively, core level X-ray emission spectroscopy can be used, but the emission
line positions are strongly affected by spin-orbit interaction. However, due to
the energy transfer from the photon to the excited core electron, the same information
as in XANES is probed in high energy resolution off-resonant spectroscopy (HEROS).
Based on the Kramers–Heisenberg theory, we propose a new approach for ionization
threshold determination which is free of the limitations encountered in XANES-based
determination of the core state energy. Namely, the value of core state energy
can be determined analytically using a few HEROS spectra recorded with significantly
higher spectral resolution. This approach provides a basis for the universal physical
oxidation state determination method.

text: Understanding high-temperature unconventional superconductivity has become
a long-lasting problem in which the cuprates stand as central reference materials.
Given this impasse, the recent discovery of superconductivity in analogous nickelate
thin films represents a fundamental breakthrough calling for the identification
of additional materials in this class. In particular, thermodynamically more robust
systems are required to “upgrade” nickelate superconductors from thin films to
bulk samples. Here, we contribute in this direction by reporting the synthesis
of the new single-layer T′ Pr2NiO3F compound, assessing this synthesis in relation
to the only previous T′ nickelate La2NiO3F, and analyzing the electronic properties
across the R2NiO3F series (R = La–Lu) via first-principles calculations. We find
that these mixed anion systems have a comparatively high degree of stability and
their synthesis enables a fine-tuning of their composition as inferred from their
characterization. Furthermore, we find that these unprecedented square-planar
nickelates hold great promise as prospective superconductors due to their exceptional
electronic structure.

text: Homogeneous catalysts immobilized on metal oxides often have different catalytic
properties than in homogeneous solution. This can be either activating or deactivating
and is often attributed to interactions of catalyst species with the metal oxide
surface. However, few studies have ever demonstrated the effect that close associations
of active sites with surfaces have on the catalytic activity. In this paper, we
immobilize H2Ru(PPh3)2(Ph2P)2N–C3H6–Si(OEt)3 (3) on SiO2, Al2O3, and ZnO and interrogate
the relationship to the surface using IR, MAS NMR, 1H–31P HETCOR, and XAS spectroscopies.
We found that while there are close contacts between the P atoms of the complex
and all three metal oxide surfaces, the Ru–H bond only reacts with oxygen bridges
on SiO2 and Al2O3, forming new Ru–O bonds. In contrast, complex 3 stays intact
on ZnO. Comparison of the catalytic activities of our immobilized species for
CO2 hydrogenation to ethyl formate showed that Lewis acidic metal oxides activate,
rather than deactivate, complex 3 in the order Al2O3 > ZnO > SiO2. The Lewis acidic
sites on the metal oxide surfaces most likely increase the productivity by increasing
the rate of esterification of formate intermediates.

text: Rh(I) NHC and Rh(III) Cp* NHC complexes (Cp*=pentamethylcyclopentadienyl,
NHC=N-heterocyclic carbene=pyrid-2-ylimidazol-2-ylidene (Py−Im), thiophen-2-ylimidazol-2-ylidene)
are presented. Selected catalysts were selectively immobilized inside the mesopores
of SBA-15 with average pore diameters of 5.0 and 6.2 nm. Together with their homogenous
progenitors, the immobilized catalysts were used in the hydrosilylation of terminal
alkynes. For aromatic alkynes, both the neutral and cationic Rh(I) complexes showed
excellent reactivity with exclusive formation of the β(E)-isomer. For aliphatic
alkynes, however, selectivity of the Rh(I) complexes was low. By contrast, the
neutral and cationic Rh(III) Cp* NHC complexes proved to be highly regio- and
stereoselective catalysts, allowing for the formation of the thermodynamically
less stable β-(Z)-vinylsilane isomers at room temperature. Notably, the SBA-15
immobilized Rh(I) catalysts, in which the pore walls provide an additional confinement,
showed excellent β-(Z)-selectivity in the hydrosilylation of aliphatic alkynes,
too. Also, in the case of 4-aminophenylacetylene, selective formation of the β(Z)-isomer
was observed with a neutral SBA-15 supported Rh(III) Cp* NHC complex but not with
its homogenous counterpart. These are the first examples of high β(Z)-selectivity
in the hydrosilylation of alkynes by confinement generated upon immobilization
inside mesoporous silica.
