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.

text: We report on sensing properties of ordered mesoporous nanostructures of In2O3
synthesized by nanocasting procedure towards NO2. The nanostructured material
shows improved recover times and higher responses compared to non nanostructured
material at low operating temperatures (100–150°C) thus allowing the use for low
power NO2 sensors. These properties may be related to fast oxygen in and out propagation
facilitated by an enhanced surface accessibility of the nanostructure.

text: A model is proposed for the drop in electronic resistance of n-type semiconducting
indium oxide (In2O3) upon illumination with light (350 nm, 3.5 eV) as well as
for the (light-enhanced) sensitivity of In2O3 to oxidizing gases. Essential features
of the model are photoreduction and a rate-limiting oxygen-diffusion step. Ordered,
mesoporous In2O3 with a high specific surface area serves as a versatile system
for experimental studies. Analytical techniques comprise conductivity measurements
under a controlled atmosphere (synthetic air, pure N2) and temperature-resolved
in-situ Fourier transform infrared (FTIR) spectroscopy. IR measurements reveal
that oxygen vacancies form a donor level 0.18 eV below the conduction band.

text: Poröse Funktionsmaterialien wie halbleitende Metalloxide, Kohlenstoff-Formen
oder auch Silica werden aktuell von verschiedenen Wissenschaftsdisziplinen intensiv
für Bereiche der Energiespeicherung, Sensorik, Katalyse und Stofftrennung erforscht.
Im Beitrag werden schwerpunktmäßig geordnet-mesoporöse Silica-Materialien behandelt,
die seit etwa 20 Jahren synthetisch zugänglich sind. Neben den Grundlagen der
Herstellung über ein Templat-Verfahren werden im Beitrag auch drei Experimente
vorgestellt, die im Chemieunterricht oder Schülerlabor durchgeführt werden können.
Zudem wird gezeigt, dass sich verschiedene Aspekte aus dem Kompetenzbereich Fachwissen
mit Hilfe des Themas „Mesoporöse Silica“ miteinander vernetzen lassen.

text: Crystalline, mesoporous alumina (Al2O3) materials with specific surface areas
up to 400 m2 g–1 have been synthesized by means of structure replication (nanocasting)
using CMK-8 carbon as a structure matrix. A crucial step during this synthesis
procedure is the conversion of aluminum nitrate into aluminum hydroxide by treatment
with ammonia vapor. The impact of this step was investigated in some detail. Prolonged
vapor treatment has a positive impact on the crystallinity of the final Al2O3
products but at the same time leads to loss of mesoscopic structural order and
porosity.

text: Nanoporous ZnO powders with high surface-to-mass ratios (SMR) between 15 and
70 m2 g−1 are synthesized, structurally characterized, and studied by time-resolved
photoluminescence (PL). A strong dependence of the recombination dynamics and
spectral width on SMR is observed at T = 10 K, and pronounced disorder-induced
effects are found in the temperature dependence. Both the thermally induced shift
of the PL maximum and the spectrally integrated PL intensity are interpreted by
appropriate theoretical models. This consistent quantitative analysis of the experimental
data yields a characteristic energy of 15 meV for the disorder scale in the nanoporous
ZnO sample with an intermediate SMR.

text: We report the correlation of the aging of Pd-doped SnO2 methane sensors with
the change of the oxidation state of Pd. Mesoporous SnO2 doped with palladium
species was prepared and exposed to different gas mixtures at high temperature
(600 °C) to simulate long term usage. After each exposure step a fraction of the
sample was cooled down to “freeze” the current oxidation state of Pd which was
then analyzed by X-ray Absorption Near-Edge Spectroscopy (XANES) using the 'white
line' (i.e. the absorption peak corresponding to the transition from the 2p3/2
core level to unoccupied 4 d states) intensity of the L(III) edge as a probe for
the oxidation state. The Pd oxidation state correlates with the response of the
resistive SnO2 sensor to methane gas, as determined by measuring the gas response
to different concentrations of methane. Samples treated with 5000 ppm methane
in air show a significant reduction of Pd(II) to Pd(0), depending clearly on the
carrier gas (synthetic air, pure nitrogen) and on the temperature (600 °C vs.
300 °C).

text: Capacitive sensors are the most commonly used devices for the detection of
humidity because they are inexpensive and the detection mechanism is very specific
for humidity. However, especially for industrial processes, there is a lack of
dielectrics that are stable at high temperature (>200 °C) and under harsh conditions.
We present a capacitive sensor based on mesoporous silica as the dielectric in
a simple sensor design based on pressed silica pellets. Investigation of the structural
stability of the porous silica under simulated operating conditions as well as
the influence of the pellet production will be shown. Impedance measurements demonstrate
the utility of the sensor at both low (90 °C) and high (up to 210 °C) operating
temperatures.

text: We report the synthesis of mesoporous tin dioxide (SnO2) materials with well-defined
particle morphology. The products consist of uniform spheres with a diameter of
5 μm. The spheres are hierarchically porous with two distinct pore modes of 5.0
nm and 52 nm, respectively. This special porosity is the result of a synthesis
procedure which involves a ‘hard templating’ (nanocasting) process. The product
forms an approximately homogeneous monolayer of spheres on a sensor substrate
and shows promising response to methane gas with low cross-sensitivity to water.
The structural properties and gas-sensing performance are compared with a mesoporous
SnO2 material without defined morphology, prepared by a ‘soft templating’ procedure.

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.
