  text: The sorption properties of mixed-linker CAU-10 type metal organic frameworks
    (MOFs), [Al(OH)(1,3-BDC-X)n(1,3-BDC-SO3H)m] with 1,3-BDC = 1,3-benzenedicarboxyliate,
    X = H, NO2 or OH, 0.76 ≤ n ≤ 0.89 and 0.11 ≤ m ≤ 0.24, can be varied by surface
    modification through variation of the respective linker molecules. It is thus
    possible to design surface-modified CAU-10 type MOFs with variable affinity and
    accessibility of the pores for water vapour. When used as a dielectric in a capacitor,
    the MOF material will change its permittivity depending on the amount of physisorbed
    water; this is the working principle of capacitive humidity sensors. Three different
    mixed-linker compounds with CAU-10 structure are compared regarding their water
    sorption and impedance characteristics. A setup was developed allowing the characterization
    of the MOF samples under exposure to different relative humidity values in air
    by impedance spectroscopy. Interpretation of the results by means of standard
    models shows that the MOFs are qualified for functional layers of capacitive humidity
    sensors. Since the prepared MOFs are more temperature-stable than many commonly
    used polymers they offer the potential to build a new generation of high-temperature
    (up to 350 °C) humidity sensors.

  text: Ordered, bimodal mesoporous CMK-5 carbon is prepared by using mesoporous SBA-15
    silica as a structural mold. The carbon material is chemically modified by oxidative
    treatment with acidic persulfate solution. This leads to the creation of oxygen-containing
    functionalities at the pore walls of the carbon (up to 13 wt% oxygen), as confirmed
    by IR spectroscopy. The oxidative treatment is carried out before removal of the
    silica mold which ensures that only one of the two distinct modes of mesopores
    (namely, the intra-tubular pores) is affected; the other mode (inter-tubular pores)
    is protected from oxidation by the presence of the silica mold. This is proven
    by water vapor physisorption analysis. The oxidatively treated (intra-tubular)
    pores are significantly more polar and, hence, better wettable than the untreated
    (inter-tubular) pores.

  text: Characterization and application of (meso)porous materials often require information
    about the density of the respective samples. For example, the BET surface area
    is, by definition, normalized to the sample mass; hence, any comparison between
    samples of different composition needs to take into account their respective densities.
    Literature data on the densities of porous materials are scarce. Frequently, only
    bulk-phase densities are available which sometimes differ from those of porous
    samples, especially for amorphous systems, such as silica or carbon. The apparent
    density, i.e. the density of the sample excluding the gas-accessible pore volume,
    is typically determined by helium gas pycnometry utilizing specialized pycnometers.
    We demonstrate how to obtain the same data from standard N2 physisorption measurements
    as part of the regular measurement routine. We evaluate the method by reference
    measurements utilizing a non-porous reference sample (glass rod) to confirm the
    validity of the method. Then we present results on apparent density measurements
    of several mesoporous silica materials (MCM-41, MCM-48, SBA-15, KIT-6), mesoporous
    carbon (CMK-3, -5, -8, -9), and a variety of mesoporous metal oxides obtained
    by nanocasting.

  text: Metal–organic frameworks (MOFs) are crystalline microporous materials with
    tunable chemical and physical properties. By combining various metal clusters
    with different interconnecting organic linkers, the pore structure, crystallinity,
    as well as the surface properties can be modified. In the present work, modification
    of the organic linker molecules is utilized to synthesize CAU-10 type MOFs with
    variable affinity of the pore surface to water. In principle, this should influence
    the accessibility of the pores for water vapor and therefore offer a tool to control
    its sorption properties. For a deeper understanding we studied the water sorption
    characteristics and compared the results to the conductive and dielectric properties
    studied by impedance spectroscopy. Spectra in a wide frequency range from 1 mHz
    to 1 MHz were recorded. Data analysis is performed using the Havriliak–Negami
    model. The MOFs are also tested as sensitive layers for capacitive humidity sensing
    by correlating the change in permittivity of the materials with the amount of
    physisorbed water. Such an MOF-based sensor was tested with respect to environmental
    monitoring and compared to a commonly used commercial humidity sensor.

  text: A variety of metal nitrates were filled into the pores of an ordered mesoporous
    CMK-3 carbon matrix by solution-based impregnation. Thermal conversion of the
    metal nitrates into the respective metal oxides, and subsequent removal of the
    carbon matrix by thermal combustion, provides a versatile means to prepare mesoporous
    metal oxides (so-called nanocasting). This study aims to monitor the thermally
    induced processes by thermogravimetric analysis (TGA), coupled with mass ion detection
    (MS). The highly dispersed metal nitrates in the pores of the carbon matrix tend
    to react to the respective metal oxides at lower temperature than reported in
    the literature for pure, i.e., carbon-free, metal nitrates. The subsequent thermal
    combustion of the CMK-3 carbon matrix also occurs at lower temperature, which
    is explained by a catalytic effect of the metal oxides present in the pores. This
    catalytic effect is particularly strong for oxides of redox active metals, such
    as transition group VII and VIII metals (Mn, Fe, Co, Ni), Cu, and Ce.

  text: Ordered mesoporous In2O3 particles of variable size synthesized by the nanocasting
    method are used for preparation of resistive gas-sensing layers. Light activation
    by a LED (blue light, 460 nm) permits room-temperature ozone sensing. Apart from
    differences in base-line resistance in sensing layers containing small (diameter
    approx. 170 nm) or large particles (approx. 870 nm), differences in the response
    amplitude and response time constant are also observed. Signal stabilization is
    achieved faster for small particles. In addition, sensors show a particle size-dependent
    reaction threshold for low ozone concentration. Larger particles show negligible
    response to 50 ppb ozone whereas a significant response is observed for the small-particle
    sensors. A simple model based on geometrical properties and formation of depletion
    layers explaining the observed behavior is presented.

  text: Cobalt oxide spinel (Co3O4) with an ordered nanostructure is used as a resistive
    gas sensor for carbon monoxide (CO) in low ppm concentrations. The operating temperature
    has a strong impact on the concentration-dependent sensing behavior. At lower
    temperature (473 K) the sensor response is governed mainly by surface coverage
    with CO and/or CO2, whereas at higher temperature (563 K) oxygen diffusion in
    the crystal lattice of Co3O4 strongly affects the sensing behavior.

  text: Catalysis plays a central role in many fields of life, e.g., in biochemical
    processes, to reduce energy costs and resources in chemical industry and to decrease
    or even avoid environmental pollution and in energy management. Porous alumina
    (Al2O3) is an essential material in various applications, especially as a support
    material for catalysts. It is often prepared by nanocasting using porous carbon
    materials that serve as rigid structure matrices. In this work, an alternative
    way to synthesize mesoporous Al2O3 by using hydrogels as porogenic material is
    presented. Hydrogels can easily be patterned by light and used to imprint their
    structure onto alumina opening a new approach to fabricate patterned Al2O3. The
    hydrogels used in this work are based on poly(dimethylacrylamide) and were photo-chemically
    cross-linked. Followed by a nanocasting process, mesoporous alumina samples were
    synthesized and characterized by N2 physisorption and X-ray diffraction. The cross-linker
    amount in the polymer network was varied and the influence on the properties of
    the Al2O3 is analyzed.

  text: The synthesis of a periodically ordered, nanostructured composite consisting
    of CoFe2O4 and BaTiO3 is presented. In a first step, mesoporous CoFe2O4 is prepared
    by the structure replication method (nanocasting) using mesoporous KIT-6 silica
    as a structural mold. Subsequently, BaTiO3 is created inside the pores of CoFe2O4
    by the citrate route, resulting in a well-ordered composite material of both phases.
    The two components are known for their distinct ferroic properties, namely ferrimagnetism
    (CoFe2O4) and ferroelectricity (BaTiO3), respectively. Therefore, this proof of
    synthesis concept offers new perspectives in the fabrication of composite materials
    with multiferroic properties.

  text: Ordered mesoporous silica phases (e.g. KIT-6, SBA-15) are used as structure
    matrices for negative replica structures of mesoporous In2O3. We present a detailed
    study on how the controlled synthesis of mono-, bi- and trimodal pore systems
    in the products is accomplished by systematic variation of the procedure of infiltrating
    a precursor species (In(NO3)3) into the pores of the silica matrix and subsequent
    thermal conversion into In2O3. Melt impregnation and conversion in a closed reactor
    facilitates a one-step casting process for ordered mesoporous indium oxide (In2O3).
    We present a model based on variation of the pore filling.

  text: Recently indium oxide (In2O3) attracted attention as a material for sensing
    layers in semiconducting gas sensors. Compared to frequently investigated materials
    like tin dioxide (SnO2), tungsten trioxide (WO3), or gallium oxide (Ga2O3) indium
    oxide offers some unique properties. The most prominent one is its selectivity
    to oxidizing gases such as ozone (O3) or nitrogen dioxide (NO2) at low operating
    temperatures (<150°C). Combined with the photoreduction properties of nanocast,
    porous In2O3 highly selective sensing layers with a fast response can be prepared.
    In some cases even room temperature measurements are possible; therefore this
    material allows for designing low-power sensors without the need for special sensor
    substrates (e.g., μ-hotplates). Detailed analysis of the sensing mechanism reveals
    that known sensing models are not able to describe the observed effects. Therefore
    a new sensing model for ordered nanoporous In2O3 is presented which will be applicable
    for nonstructured material too.

  text: In this paper, the development and validation of a shield prototype for resistive
    sensor array characterization with Arduino UNO, a platform based on ATmega328
    microcontroller provided by ATMEL, is reported. The resistance variation of the
    sensor can be evaluated by properly choosing the capacitance value and by measuring
    the period (frequency) of a custom inverter-based oscillator. The GUI and the
    developed firmware are able to perform the real-time monitoring of the sensor
    responses. The developed shield is able to measure the response of up to six sensors
    under UV radiation by means of LED devices. First results carried out with resistive
    sensors based on mesoporous In2O3-based material under UV light exposure are reported.

  text: Due to their unique properties, ordered mesoporous carbon (OMC) materials
    prepared by nanocasting have raised great attention in recent years. Their synthesis
    usually comprises multiple cycles of impregnating a porous structure matrix with
    an aqueous solution of a suitable precursor, such as sucrose or other, often hazardous,
    compound. We present a more straightforward variation of this method by using
    fructose as the precursor compound. By using a solvent-free melt of the precursor,
    the impregnation requires only a single step. After carbonization by thermal decomposition
    and removal of the mesoporous silica structure matrix (SBA-15), ordered mesoporous
    carbon with one (CMK-3) or two (CMK-5) pore modes in two-dimensional, hexagonal
    symmetry (p6mm) is obtained.

  text: Nanoporous Materials, like carbons, silica and semiconducting metal oxides,
    play a major role in recent scientific research, especially in the fields of energy
    storage, catalysis, material separation and sensor technology. Thus, our aim is
    to focus on simple synthesis concepts for these materials, such as soft matter
    templating or nanocasting, which can be easily introduced by means of appropriate
    models in school chemistry education or school laboratories. In addition to facile
    and realizable syntheses in school, several experiments concerning catalysis and
    gas sensing will be presented, too. By these experiments the characteristics of
    nanoporous materials can be obviously demonstrated and additionally, these experiments
    can serve as a starting point for further experiments that could easily be developed
    by students themselves, particularly in relation to environmental issues.

  text: Ordered mesoporous carbon with a high heteroatom (N, O) content was prepared
    by nanocasting from a melt of a eutectic mixture of fructose and urea (60/40 wt.-%;
    melting temperature ca. 65 °C). These precursor compounds are cheap and environmentally
    friendly. The material possesses enhanced pore-wall surface polarity as compared
    to that of mesoporous carbon prepared by the same technique without urea. This
    was verified by water sorption analysis. As a result, the heteroatom-modified
    material shows higher sorption capacity for the uptake of heavy metal ions (Cu2+)
    from aqueous solution, which may be interesting for potential application in wastewater
    cleaning.

  text: The light-enhanced NO2 sensing behavior of mesoporous In2O3 is measured and
    interpreted by means of a new sensing model. The model aims at explaining (i)
    the drop in electronic resistance of n-type semiconducting In2O3 under UV light
    exposure, (ii) the light-enhanced reaction to oxidizing gases, and (iii) the faster
    reaction and regeneration in mesoporous In2O3 as compared to non-porous material.
    Contrary to the conventional double Schottky model the dominating factor for the
    change in resistance is a change of oxygen vacancy donor states (0.18 eV below
    the conduction band) in the bulk phase due to photoreduction, instead of chemisorption.
    For the faster reaction and regeneration we propose an explanation based on enhanced
    oxygen diffusion in the In2O3 crystal lattice, specifically dominant in the mesoporous
    structure. The response of ordered mesoporous In2O3 to NO2 is stronger than in
    case of unstructured bulk material (with an average grain size of ca. 40 nm).
    The reaction is significantly accelerated by illuminating the samples with UV
    light. However, the response of the mesoporous material is weaker in the illuminated
    case.

  text: Nanostructure-related magnetic properties are investigated systematically
    for various mesoporous cobalt oxide (Co3O4) and cobalt ferrite (CoFe2O4) spinel
    phases. Synthesis of the materials by nanocasting offers the opportunity to obtain
    materials which are different from each other with respect to both specific surface
    area and crystallite size. As a result, the respective contributions of two types
    of interfaces, namely, “solid–gas” and “solid–solid” interfaces, to the magnetic
    ordering can be distinguished. Structural characterization of the porous materials
    by X-ray diffraction, N2 physisorption, and electron microscopy as well as investigation
    of the magnetic behavior (field-dependent magnetization and temperature-dependent
    susceptibility) are presented.

  text: Ordered mesoporous materials have great potential in the field of gas sensing.
    Today various template-assisted synthesis methods facilitate the preparation of
    silica (SiO2) as well as numerous metal oxides with well-defined, uniform and
    regular pore systems. The unique nanostructural properties of such materials are
    particularly useful for their application as active layers in gas sensors based
    on various operating principles, such as capacitive, resistive, or optical sensing.
    This review summarizes the basic aspects of materials synthesis, discusses some
    structural properties relevant in gas sensing, and gives an overview of the literature
    on ordered mesoporous gas sensors.
