  text: Mesoporous In2O3, synthesized by a nanocasting procedure, is used as a resistive
    gas sensor for ozone in very low concentrations (from 20 ppb to 2.4 ppm) at room
    temperature. Its sensing performance is substantially increased by illumination
    with blue light (460 nm, 2.7 eV). For low ozone concentrations the sensor response
    increases with increasing humidity. However, higher humidity also results in the
    occurrence of a saturation of the response at lower ozone concentrations; this
    is rationalized by assuming a poisoning of surface active sites by hydroxyl groups.

  text: 'Precipitation of zinc sulfide particles is a very rapid process, and monitoring
    of the particle growth is experimentally very demanding. Applying a liquid jet
    flow cell, we were able to follow zinc sulfide particle formation on time scales
    down to 10−5 s. The flow cell was designed in such a way that data acquisition
    on the microsecond time scale was possible under steady-state conditions along
    a liquid jet (tubular reactor concept), allowing SAXS data accumulation over a
    time scale of minutes. We were able to monitor the growth of zinc sulfide particles
    and found experimental evidence for very rapid particle aggregation processes
    within the liquid jet. Under the experimental conditions the particle growth is
    controlled by mass transfer: i.e., the diffusion of the hydrogen sulfide into
    the liquid jet.'

  text: We report the structural characterization and gas sensing properties of mesoporous
    SnO2 synthesized by structure replication (nanocasting) from ordered mesoporous
    KIT-6 silica. The products show a high thermal stability with no structural loss
    up to 600 °C and only minor decrease in specific surface area by 18% at 800 °C,
    as proven by powder X-ray diffraction (PXRD), transmission electron microscopy
    (TEM), and nitrogen physisorption. In particular, the samples turn out to be much
    more stable than porous SnO2 materials prepared by sol–gel-based synthesis procedures
    for comparison. The thermal stability facilitates the utilization of the materials
    as sensors for combustible gases which react at high temperatures; test measurements
    reveal promising responses to methane (CH4) as an example.

  text: In2O3 with ordered, uniform mesoporosity is prepared by nanocasting, using
    various porous silica phases (KIT-6, SBA-15) as structure matrices. The In2O3
    particles exhibit well-defined morphologies (spherical or ellipsoidal, depending
    on the choice of silica matrix) and quite uniform sizes in the range of a few
    hundred nanometers. The regular morphology of the In2O3 particles is not associated
    with the morphological properties of the silica matrices. Instead, it is the result
    of the growth mechanism of In2O3 inside the silica pores; this mechanism is investigated
    in some detail. Hence, the nanocasting method offers a versatile and simple way
    of creating mesoporous In2O3 with regular morphology; this will be beneficial
    for many applications that require well-defined morphological properties, such
    as gas sensing or catalysis.

  text: We report the synthesis of monodisperse, spherical periodic mesoporous organosilica
    (PMO) materials. The particles have diameters between about 350 and 550 nm. They
    exhibit a regular core-shell structure with a solid, non-porous silica core and
    a mesoporous PMO shell with a thickness of approximately 75 nm and uniform pores
    of about 1.7 nm. The synthesis of the core and the shell is carried out in a one-pot,
    two-stage synthesis and can be accomplished at temperatures between 25 and 100 °C.
    Higher synthesis temperatures lead to substantial shrinking of the solid core,
    generating an empty void between core and shell. This leads to interesting cavitation
    phenomena in the nitrogen physisorption analysis at 77.4 K.

  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."
