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.

text: Periodically ordered mesoporous magnesium oxide was synthesized in a double
replication procedure. Mesoporous SBA-15 silica and CMK-3 carbon were successively
used as hard structure matrixes. The carbon pore system was infiltrated with Mg(NO3)2,
which was then converted to MgO at 573 K; the carbon matrix was finally removed
by thermal combustion. The structure of the mesoporous MgO corresponds to that
of the original SBA-15 silica. The products consist of hexagonally arranged cylindrical
mesopores and crystalline pore walls. The efficiency of the replication series
was studied by variation of the infiltration method and comprehensive pore size
analysis of all involved mesoporous materials. The in situ formation of MgO inside
the CMK-3 carbon pore system was monitored by thermal analysis. Postsynthetic
treatment of the products at 823 K in a vacuum prior to removal of the carbon
matrix was found to improve the crystallinity but to diminish the periodic order
of the pore system.

text: The early stages of ZnS nanoparticle growth from supersaturated solution are
investigated in situ by stopped-flow UV absorption spectroscopy with a time resolution
of 1.28 ms. A model for data analysis is suggested which makes it possible to
study both the average particle radius and the concentration. The average radii
lie in the sub-nanometer range. During the first 40 ms, growth is predominantly
governed by ripening.

text: The formation of mesoscopically ordered silica/surfactant composites under
acidic synthesis conditions is studied by time-resolved in-situ small-angle X-ray
scattering (SAXS) using synchrotron radiation. Benzene is used a an additive which
acts as a weak swelling agent although most of the benzene molecules are found
to reside near the surfactant/silicate interface region rather than in the micelle
cores. With increasing relative amounts of benzene, the curvature of the micellar
aggregates decreases, which finally leads to a transition from (hexagonally) rodlike
to lamellar; a mechanism for this change in curvature is suggested.

text: Long-chain n-alkylamine surfactants have been used as structure-directing
agents in the synthesis of mesoporous aluminophosphates by a highly cooperative
formation mechanism in an alcoholic system. Small amounts of water in the synthesis
mixture play a significant role in the hydrolysis of the aluminum precursor (Al[OiPr]3)
and are important for the quality of the mesostructured products. The materials
exhibit disordered mesostructures, the stability and structural order of which
can be improved by a postsynthetic thermal treatment. The products are then stable
enough for the removal of the surfactant molecules by acidic solvent extraction,
yielding surface areas up to 690 m2/g.

text: Mesostructured aluminophosphate/dodecyl phosphate composite materials were
synthesized under aqueous and alcoholic conditions. The syntheses were monitored
by temperature- and time-resolved in-situ small-angle X-ray scattering (SAXS).
In the aqueous synthesis, a lamellar mesostructure is formed within the first
few minutes of the reaction; this structure maintains a constant d spacing independent
of the reaction time and temperature. The alcoholic synthesis at low temperature
yields a mixture of a lamellar and a supposedly inverted hexagonal mesostructure.
SAXS investigations show that these two phases evolve competitively. The lamellar
structure is favored by higher temperatures and/or longer synthesis times; above
∼70 °C it is formed exclusively. Mixtures of both phases can be isolated as solid
materials, but thermal analysis shows that the inverted hexagonal product transforms
into the lamellar phase at ∼35−43 °C. The alcoholic synthesis is a highly cooperative
reaction; the pure surfactant/alcohol systems are not lyotropic as long as the
inorganic reactants are absent. In comparison, the surfactant/water system with
the same surfactant concentrations as employed for the aqueous syntheses is lyotropic
with a lamellar structure.

text: The atomic structure of ordered mesostructured aluminophosphates with dodecyl
phosphate as the structure-directing template was investigated by multinuclear
solid-state NMR. Two different types of materials were studied: one with the
template headgroup as the only phosphate source and one where additionally phosphoric
acid was used in the synthesis. All 31P and 27Al NMR resonances can be subdivided
into three groups depending on the sample composition. Furthermore, 2D heteronuclear
correlation NMR measurements allow a conclusive and unambiguous identification
of the phosphate headgroup resonances of the template molecules and the determination
of water and/or hydroxyl units. Most notably, there is an obvious correlation
between the d001 values of the samples as measured by powder X-ray diffraction
and the appearance of the various groups of 27Al and 31P resonances.

text: Mesostructured aluminophosphate / surfactant composite materials were prepared
from aqueous and alcoholic systems. Syntheses in ethanol or methanol, respectively,
lead to mixtures of two nanostructured phases. One of these consists of hexagonally
arranged rod-like assemblies of the surfactant molecules with the head groups
located in the centres, encapsulating the inorganic aluminophosphate; the other
is lamellar. The syntheses were monitored by in-situ temperature- and time-resolved
small angle X-ray scattering (SAXS).

text: We report on the synthesis of lamellar mesostructured aluminophosphate composites
which contain variable relative amounts of aluminium oxide species in the core
regions of the lamellae; this is investigated quantitatively by Al K-edge XANES
spectroscopy. Templating is achieved by the utilisation of monododecyl phosphate
surfactant. If no phosphorous source (such as H3PO4) is used for the synthesis,
the phosphate head groups of the surfactant become incorporated into the inorganic
network to form similar lamellar aluminophosphate structures. Thus, the surfactant
serves as both template and reactant.
