Abstract：The emission of volatile organic compounds(VOCs)not only contributes to air pollution,but also poses serious threat to human health.Therefore,it is urgent to effectively control VOCs source emissions.Catalytic oxidation technology is considered as a promising VOCs treatment method for its high treatment efficiency and less by-products,which has been widely used in the treatment of VOCs-containing waste gas in various industries.Catalyst is the core of catalytic oxidation technolo-gy,and transition metal oxides are excellent catalytic oxidation materials for VOCs oxidation due to their wide natural source and variable valence states.Manganese oxide has excellent oxidation-reduc-tion activity due to its abundant valence state,which has become a hot spot of VOCs catalytic oxida-tion materials.In this article,the research progress of different manganese oxide catalysts in recent years was reviewed,and the preparation methods and catalytic VOCs oxidation performance of single manganese oxide,metal-doped modified manganese oxide and composite manganese oxide were sum-marized and discussed respectively.Finally,the remaining challenges and future development of VOCs catalytic oxidation by manganese-based oxides are discussed.
