text: The synthesis and characterization of ordered mesoporous In2O3 materials by
structure replication from hexagonal mesoporous SBA-15 silica and cubic KIT-6
silica is presented. Variation of the synthesis parameters allows for different
pore sizes and pore wall thicknesses in the products. The In2O3 samples turn out
to be stable up to temperatures between 450 °C and 650 °C; such high thermal stability
is necessary for their application as gas sensors. Test measurements show a high
sensitivity to methane gas in concentrations relevant for explosion prevention.
The sensitivity is shown to be correlated not only with the surface-to-volume
ratio, but also with the nanoscopic structural properties of the materials.

text: We report a systematic study of the photoluminescence properties of ZnO nanostructures.
In particular, mesoporous ZnO powders of varying surface-to-mass ratio are investigated
and compared to a bulk reference. At low temperatures the emission from higher-energy
states is very pronounced and even dominant for samples with high surface-to-mass
ratio.

text: We present the preparation of a semiconductor gas sensor based on ordered
mesoporous In2O3. The In2O3 was synthesized by structure replication procedure
from cubic KIT-6 silica. A detailed analysis of the morphology of the mesoporous
powders as well as of the prepared sensing layer will be shown. Unique properties
arise from the synthesis method of structure replication such as well defined
porosity in the mesoporous regime and nanocrystallites with high thermal stability
up to 450 °C. These properties are useful for the application in semiconducting
gas sensors. Test measurements show sensitivity to methane gas in concentrations
relevant for explosion prevention.

text: Halbleitende Metalloxid-Gassensoren werden sowohl im industriellen Bereich
als auch im Haushalt zur Luftüberwachung verwendet. Die Funktionsweise basiert
auf einer reversiblen Änderung des Sensorwiderstandes in Anwesenheit sowohl oxidierender
als auch reduzierender Gase, die mit einfachen Mitteln gemessen werden kann. In
diesem Artikel wird vorgestellt, wie sich die bei der Gasdetektion ablaufenden
Vorgänge mit Hilfe des Ionosorptionsmodells in Kombination mit einem einfachen
Festkörperbändermodell deuten lassen. Abschließend werden einfache, im Chemieunterricht
zu realisierende Experimente mit Gassensoren präsentiert.

text: Mesoporous SBA-15 (space group p6mm), KIT-6 (Ia3d) and KIT-5 (Fm3m) silicas,
exhibiting different 2-D and 3-D channel- or cage-like pore structure and pore
dimensions have been used as supports for iron oxide nanoparticles. The iron modification
of the silica was performed according to a frequently used impregnation technique
from aqueous iron nitrate solution. The materials were characterized by nitrogen
physisorption, X-ray diffraction, TEM–EDX, Moessbauer spectroscopy, and temperature-programmed
reduction (TPR) and tested in the catalytic decomposition of methanol. It is established
that the location and dispersion of iron oxide nanoparticles are affected by the
pore topology of the support. The most homogeneously dispersed iron oxide nanoparticles
are observed using silica host matrix exhibiting a 3-D channel-like structure
and pore diameters about 7 nm, and the thus-obtained composites exhibit high catalytic
activity and selectivity in methanol decomposition to CO and hydrogen. For all
the samples, characterized with a low mesopore volume and small pore diameters/pore
entrances, the formation of larger iron oxide particles, mainly located on the
outer surface, is observed. Inhomogeneously dispersed iron oxide particles with
a large fraction of isolated, strongly interacting with the support, iron species,
and possessing low catalytic activity and usually high selectivity to methane,
are found for the silicas with relatively larger pores/pore entrances.

text: Various measures to optimise the impregnation of mesoporous CMK-3 carbon and
SBA-15 silica matrices with metal nitrates for the synthesis of mesoporous metal
oxides by structure replication are investigated. The effect of surface modification
of the matrix pores, the choice of a solvent with suitable polarity, and the concentration
of the metal nitrate solution are studied in detail. The efficiency of pore loading
is monitored by nitrogen physisorption measurements. The creation of polar functions
at the pore surface of CMK-3 carbon is shown to increase the impregnation efficiency
substantially while maximizing the pore wall polarity of SBA-15 silica by increasing
the amount of free silanol groups does not have any significant impact. The choice
of a less polar solvent (THF instead of water) has a positive effect on the wettability
of CMK-3 carbon in the first impregnation cycle but turns out to be disadvantageous
in the second cycle; a similar trend is observed for variation of the metal salt
concentration.

text: 'Iron (III) containing nanoparticles with superparamagnetic behaviour are
prepared via deposition on various mesoporous supports (MgO, CeO2 and SBA-15).
XRD, TEM-EDX, N2 physisorption, FTIR, and Moessbauer spectroscopy are used for
their characterization. The reductive properties and catalytic behaviour in methanol
decomposition of the materials are also studied. Depending on the chemical nature
of the support, the predominant formation of: isolated iron species, strongly
interacting with the support (for SBA-15), mixture of hematite and binary MgFe2O4
nanoparticles (for MgO) or almost homogeneously dispersed hematite particles (for
CeO2) are observed. The state of iron species strongly affects their catalytic
properties. The favorable effect of the support mesoporosity on the catalytic
activity is most pronounced for the iron modified CeO2.'

text: Nanoporous semiconducting metal oxide materials (In2O3, WO3) with uniform
pore systems, large specific surface areas (80 m2 g−1), and pore-wall crystallinity
were prepared by structure replication, using KIT-6 silica as a template. The
products show improved properties as gas sensors (for methane or butanone) as
compared to non-porous samples. In addition, porous WO3 samples with comparable
porosity (prepared by conventional ‘soft templating’, using pluronic P123), which
are amorphous on the atomic length scale show poorer gas sensitivity, indicating
that crystallinity is a crucial factor in the sensing process.

text: The growth of ZnS nanoparticles during precipitation from aqueous solution
is studied by in situ stopped-flow UV absorption spectroscopy at temperatures
between 283 and 323 K. Particle growth is marked by substantial ripening during
the first 60 ms. Kinetic data suggest that a ripening mechanism by coalescence
(oriented attachment) is predominant over Ostwald ripening, although the latter
seems to coexist to a significant degree at early temporal stages, predominantly
at low temperatures.

text: In recent years, a lot of research activity has focused on the synthesis of
new ordered porous materials by utilization of porous matrices as templates. Since
the matrices are themselves created by templating procedures, the entire process
can be envisaged as “repeated templating”. This review describes recent conceptual
developments in the field of structure replication and summarizes the large number
of publications on new functional materials prepared by this method.

text: Mesoporous ceria was synthesized by using both CMK-3 carbon and SBA-15 silica
as structure matrices. All products exhibit uniform mesopores with diameters of
5-6 nm in a two-dimensional periodic arrangement in addition to varying amounts
of interparticle porosity. The gas sensing properties (methane detection) of ordered
mesoporous ceria was compared to a non-porous sample.

text: Mesoporous CeO2 was synthesised by using CMK-3 carbon as a structure matrix.
Nitrogen physisorption, powder X-ray diffraction, transmission electron microscopy
(TEM), selected-area electron diffraction (SAED), energy-dispersive X-ray (EDX),
X-ray absorption near-edge structure (XANES), and thermal (TG/MS) analysis were
used for their characterisation. Methanol decomposition to hydrogen, CO, and methane
was used as a catalytic test reaction. The obtained products exhibit uniform pores
with a diameter of ca. 5 nm in a two-dimensional hexagonal periodic arrangement,
as well as interparticle porosity, broadly distributed around ca. 35 nm; the specific
surface area is 148 m2 g−1. The pore walls are polycrystalline. The polycrystalline
nature and high surface-to-volume ratio of the products is reflected in an increased
signal intensity in X-ray absorption spectroscopy. The synthesis of CeO2 from
Ce(NO3)3 within the pores of the carbon matrix and the subsequent thermal combustion
of the carbon is monitored by thermal analysis. Catalytic tests reveal that the
activity of the mesoporous products in methanol decomposition are substantially
higher than for a non-porous sample.

text: "The authors report the synthesis of nanoporous ZnO, which exhibits a periodically
ordered, uniform pore system with crystalline pore walls. The crystalline structure
is investigated by x-ray diffraction, transmission electron microscopy, and selected
area electron diffraction. The large specific surface area and the uniformity
of the pore system are confirmed by nitrogen physisorption. Raman spectroscopy
along with low-temperature photoluminescence measurements confirms the high degree
of crystallinity and gives insight into defects participating in the radiative
recombination processes.\r\nThe authors thank Günter Koch for recording the TEM
images and Marie-Luise Wolff for valuable help in the laboratory one of the authors
(M.T.) thanks Michael Fröba for the continuous support."

text: We report on the synthesis and the gas-sensing properties (CO and NO2 detection)
of mesoporous zinc oxide. A two-step structure replication method for the synthesis
is employed. In the first step mesoporous SBA-15 silica is prepared by the utilization
of self-organization of amphiphilic organic agents. This mesoporous silica is
used as the structure matrix for synthesizing mesoporous carbon CMK-3, which,
in turn, is employed for yet another replication step, using zinc nitrate as the
precursor. The resulting material is characterized by X-ray diffraction and nitrogen
physisorption and its gas-sensing properties are compared with a non-porous ZnO
sample.

text: Semiconducting metal oxides are frequently used as gas-sensing materials.
Apart from large surface-to-volume ratios, well-defined and uniform pore structures
are particularly desired for improved sensing performance. This article addresses
the role of some key structural aspects in porous gas sensors, such as grain size
and agglomeration, pore size or crack-free film morphology. New synthesis concepts,
for example, the utilisation of rigid matrices for structure replication, allow
to control these parameters independently, providing the opportunity to create
self-diagnostic sensors with enhanced sensitivity and reproducible selectivity.

text: The growth of ZnS nanoparticles by precipitation from supersaturated aqueous
solution is studied by stopped-flow UV absorption spectroscopy. The average size,
size distribution, and concentration of the particles are monitored within the
sub-second time regime with a resolution of 1.28 ms. Particle growth at these
early stages is governed by pronounced ripening. The UV absorption data strongly
suggest that growth occurs by preferential adsorption of HS- anions relative to
Zn2+ or ZnOH+ cations. Correspondingly, the initial sulfide concentration has
a much more pronounced influence on the growth kinetics than the initial zinc
concentration. These findings are verified by ζ-potential measurements which confirm
that the particle surfaces are negatively charged under near-neutral pH conditions.

text: We report on the synthesis and CO gas-sensing properties of mesoporous tin(IV)
oxides (SnO2). For the synthesis cetyltrimethylammonium bromide (CTABr) was used
as a structure-directing agent; the resulting SnO2 powders were applied as films
to commercially available sensor substrates by drop coating. Nitrogen physisorption
shows specific surface areas up to 160 m2·g-1 and mean pore diameters of about
4 nm, as verified by TEM. The film conductance was measured in dependence on the
CO concentration in humid synthetic air at a constant temperature of 300 °C. The
sensors show a high sensitivity at low CO concentrations and turn out to be largely
insensitive towards changes in the relative humidity. We compare the materials
with commercially available SnO2-based sensors.
