Catalytic activity of solvothermally-synthesized hexagonal molybdenum trioxide (h-MoO3) in epoxidation of 1-octene by tert-butyl hydroperoxide and the effect of deposition of metal (Ag, Pd, Cu) nanoparticles on the properties of catalyst have been investigated. It has been shown that silver-modified MoO3 demonstrates the highest catalytic activity and selectivity in the reaction of 1,2-epoxyoctane formation, whereas MoO3 modified with Pd nanoparticles exhibits worse catalytic performance than bare MoO3; by contrast, copper-modified MoO3 does not catalyze the epoxidation reaction. The Ag/MoO3 catalyst was also found to be active in the reaction of 1-octene oxidation by molecular oxygen at the initial stage of the oxidation process.
