Mesoporous materials as gas sensors

Chem. Soc. Rev., 2013
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.

Transformable periodic mesoporous organosilica materials

Chemical Communications, 2010
The synthesis of novel periodic mesoporous organosilica (PMO) materials incorporating a mixture of functional monomers (cis- and trans-stilbene-based) and structural monomers has been accomplished. EDX analysis of these materials in combination with HAADF imaging of OsO(4)-stained samples reveals a homogeneous distribution of trans-olefin within the co-

Mesoporous Material from Zeolite

Journal of Porous Materials, 2002
Zeolite/mesoporous molecular sieve composites (ZMC) are made using zeolites as silica-alumina source. XRD patterns of the ZMC show the peaks for both zeolite and mesoporous molecular sieve with hexagonal symmetry. Morphology of the ZMC is different from that of a physical mixture of the two components.

Modelling mesoporous materials

2002
Publisher Summary Mesoporous materials of the MCM or SBA variety are by nature organized amorphous materials. To describe their structure, it is necessary to utilize a model that can accommodate both the organization and the disorder. A structural model allows further properties of a phase to be anticipated and also allows the visualization of a ...

Polysiloxane-Modified Mesoporous Materials

Journal of Sol-Gel Science and Technology, 2000
We report the preparation of polysiloxane-modified mesoporous silica gels derived from the acid catalysed hydrolysis of tetraethoxysilane (TEOS) and oligomeric silanol terminated polydimethylsiloxane (PDMS) in the presence of the non-ionic surfactant, octaethylene glycol monohexadecyl ether.
