In this paper, the recent progress of manganese oxides catalysts for catalytic oxidation of formaldehyde are reviewed. The catalytic properties of single manganese oxides, doped manganese oxides and manganese oxide composites in catalytic oxidation of formaldehyde are introduced. Moreover, the effects of morphology, crystal structure and other factors on the catalytic performance are discussed. Besides, the reaction mechanism of partial catalyzed oxidation of formaldehyde is summarized. Finally, it is pointed out that the main research direction in the future to develop efficient, economic and environmental friendly manganese oxides catalysts. Building more defects, adding additives, doping modification and other methods, and increasing the number of active surfaces and active sites are important methods to improve the catalytic performance of manganese oxides.
