Aerobic Oxidation of Alcohol Using Molybdenum(VI) Oxide Immobilized on Mesoporous Silica

Abstract

First KIT-6 silica support, which possess ordered pores in nanoscale with high surface area, was synthesized through hydrothermal method and then Molybdenum oxide nanoparticles was located in the pores via wetness impregnation method. The prepared catalyst was characterized with different techniques such as XRD, TEM, N2 adsorption- desorption, UV-Vis, Raman and FT-IR. It is notably, existence of Molybdenum(VI) oxide was proved using Raman spectrum of MoO3-KIT-6. This catalyst was tested for alcohols oxidation reaction with air as oxidant at 80°C in solvent free conditions which can oxidize alcohols to aldehydes in relatively short times
