A mesoporous silica with incorporated vanadium (V) and tellurium (Te) (3%VTezOx-MS; z = 0-0.33), synthesized by an evaporation-induced self-assembly route, was used as a model catalyst to investigate the synergetic effect of VOx and TeOx species on propane oxidation to acrolein. It was found that V in the catalyst was predominantly present as a hig...

A series of NiO/SBA-15 (wNiO=20%) catalysts were prepared by impregnating SBA-15 with an aqueous solution of nickel nitrate followed by calcining under three different atmospheres. The resulting materials were studied with regard to the oxidative dehydrogenation of propane (ODHP) to propylene. Compared to the catalysts calcined under either static...

... Initially, mesoporous silica (denoted as m-SiO 2 ) and vanadium oxide incorporated mesoporous silica (denoted as x% V-m-SiO 2 ), where x% represents the V/Si atomic ratio in the catalyst, were synthesized using a surfactant-modied sol-gel method. [27][28][29] On the one hand, the ne control of the sol-gel process can come true the atom-level cross-linking between silicon and vanadium precursors, and on the other hand, the creation of the ordered mesoporous structure is of advantage to improve the accessibility of active species. ...
... Further calcination under NO and air-gas streams at medium temperature range led to final materials with high SSA ($440 m 2 g À1 ), high density of O À species, and even better dispersion of NiO inside the SBA-15 mesopores. Catalytic tests in ODH of propane were very promising correlating its unique nanostructure with catalytic conversion [215]. ...
