Kurzbeschreibung (Abstract)

Supported highly dispersed Vanadium oxides are of great interests for the high activity in selective oxidation of small alkanes (propane, butane) [1]. CNTs are widely used in heterogeneous catalysis as support as it is possible to manipulate them by specific chemical and thermal treatments aimed to tune the surface chemistry [2]. By incipient wetness impregnation with vanadium oxide triisopropoxide in isopropanol, highly dispersed vanadium oxide on commercial carbon nanotubes (Baytubes) with loadings of 3, 10 and 20 wt. % V were synthesized. Catalytic reactions were performed on small amounts of catalyst directly mounted onto a gold TEM grid in a microreactor, allowing direct correlation between structure and catalytic behaviors. The catalysts with lower vanadium loading show a high initial activity at 400°C but deactivate quickly.
