Structural and Catalytic Properties of a Novel Vanadium Containing Solid Core Mesoporous Shell Silica Catalysts for Gas Phase Oxidation Reaction

Abstract

A novel Vanadium containing Solid core Mesoporous shell Silica catalyst was synthesized with different Si/V ratios by co-precipitation method under neutral conditions. The synthesized materials were characterized by various techniques and Gas phase Diphenyl methane oxidation reaction. The characterization reveals that a large amount of vanadium is mainly incorporated in isolated tetrahedral environment with terminal V=O bond. Among the various Vanadium containing solid core mesoporous shell silica catalysts, the Si/V=100 ratio exhibited maximum efficiency towards Diphenyl methane to Benzophenone gas phase reaction.
