| Abstract: | With its merits of polymorphism, strong oxygen storage/release capacity, rich oxygen species, and controllability of structural defects, manganese oxide, a transition metal oxide, is frequently utilized in the thermal catalytic oxidation of benzene series. Thereinto, oxygen vacancies (OVs) with many characteristics have attracted the attention of researchers from various circles because they can efficiently promote the complete catalytic oxidation of benzene series. We reviewed the common construction methods and characterization techniques of OVs, and summarized the positive effects of several important mechanisms of OVs in manganese oxide on catalytic activity and water resistance in the catalytic oxidation of benzene series. Finally, this research concludes by summarizing and predicting novel techniques, creation mechanisms, particular processes, and their applications in the area of benzene series thermocatalytic oxidation by manganese oxide. |
