Dispersion of Phosphovanadates on Silica-Gel Chemically-Modified with Silane Coupling Agents Having an Amino Group and Their Catalytic Activities for Methanol Oxidation
Phosphotetradecavanadate (PV14) was dispersed on a silica gel chemically modified with a silane coupling agent (AnPS-SiO2) by an equilibrium adsorption method. The PV14 contents approximately correlated with the V(TV) spin contents by ESR. PV14 dispersed on AnPS-SiO2 resulted in a quite high selectivity for formaldehyde such as 97% in methanol oxidation.
