The thermal, hydrothermal, and mechanical stabilities of a wide range of ordered mesoporous materials, in particular, the molecular sieves MCM-41, MCM-48, HMS, FSM-16, KIT-1, PCH, and SBA-15, have been studied in detail using X-ray diffraction (XRD)

An alternative pathway to assemble mesoporous molecular sieve silicas is developed using nonionic alkylamines and N,N-dimethylalkylamines (SO) as structure-directing agents in acidic conditions. The synthesized mesostructures possess wormhole-like fr

Publikováno v: Journal of catalysis

The molecular designed dispersion of vanadyl acetylacetonate (VO(acac)(2)) is used to prepare MCM-48-supported vanadium oxide catalysts. The complex is deposited on the MCM-48 surface and subsequently thermally converted into the supported vanadium o
