Catalytic oxidation is a process where compounds are oxidized using catalysts. Solid catalysts exhibit several advantages over homogeneous systems, such as catalyst recovery and excellent stability. Various supported transition-metal oxides (for example: CuO, ZnO, CeO2, Fe2O3 and WO3), metal nanoparticles (for example: Pd and Ru) and polyoxometalate clusters (for example: [W10O32]4-, [Mn2ZnW(ZnW9O34)2]10- and [XW12O40]n- (X = P, Si)) have been applied to selective oxidation of organic compounds, but high associated product conversion still remains a challenge. Recently, a number of materials containing Mn3O4 have been used successfully in different catalytic applications, such as degradation of phenols, reduction of nitrobenzenes, and oxidation of various substrates that include arenes, alcohols and alkyl-substituted alkenes. Mn3O4 nanostructures having higher number of exposed catalytically active edge sites (for example, nanoparticles, nanorods and nanosheets) are especially effective for different redox reactions. These materials displayed remarkable activity in the oxidation of volatile organic compounds (VOCs) and electrocatalytic reduction of oxygen. Despite recent advances in the study of nanostructured manganese oxides as catalysts for selective oxidation catalysis, many opportunities remain to explore novel nanostructured manganese oxides materials in catalysis. Recently, our lab reported the preparation of hollow Mn3O4 nanoparticles with diameter ~31 nm and cavity of ~16 nm. We are investigating the role of these materials in selective oxidation catalysis.
