REACTIVE LATTICE OXYGEN IN MULTICOMPONENT BISMUTH MOLYBDATE CATALYST FOR OLEFIN OXIDATION
Position of the reactive lattice oxygen in the multicomponent bismuth molybdate catalyst was determined based on the isotope shift in Mo–O stretching vibration by measuring infrared and Raman spectra of the 18O-substituted catalyst with propylene oxidation using 18O2 tracer. It was proven that the oxidation reaction of olefin proceeds in accordance with the “water tank model” proposed by Moro-oka.
