VO_x/Fe₂O₃ Shell-Core Catalysts for the Selective Oxidation of Methanol to Formaldehyde.

ABSTRACT: Efficient oxidation catalysts are important in many current industrial processes, including the selective oxidation of methanol to formaldehyde. Vanadium-containing catalysts have been shown to be effective selective oxidation catalysts for certain reactions, and research continues to examine their applicability to other reactions of interest. Several VO_x/Fe₂O₃ shell-core catalysts with varying VO_x coverage have been produced to investigate the stability of VO_x monolayers and their selectivity for methanol oxidation. Catalyst formation proceeds via a clear progression of distinct surface species produced during catalyst calcination. At 300 °C the selective VO_x overlayer has formed; by 500 °C a sandwich layer of FeVO
