Various vacancies: The catalytic oxidation of benzene goes through several stages. In general, a benzene molecule adsorbed at the surface of a catalyst reacts with surface active oxygen species to obtain the final products (CO2 and H2O). During the process, surface active oxygen species are closely related to the catalyst microstructure, mainly as oxygen vacancies. Gaseous oxygen is activated at the surface to produce O2− and O−, which adsorb the surface vacancy; meanwhile, the supporter can release lattice oxygen to form a vacancy (surface and bulk), which can store and transport active oxygen species to ensure the reaction.
