    Abstract:

    Manganese oxides are often used as catalysts or support materials for many catalytic reactions due to its many advantages, such as high activity, low toxicity, abundant resources and various synthesis methods. Herein,the recent progresses of manganese oxides catalysts for catalytic oxidation of HCHO have been summarized, the catalytic properties of single manganese oxides, doped manganese oxides and manganese oxide composites in the catalytic oxidation of formaldehyde were introduced, and the main factors that influence the catalytic properties have been reviewed in terms of morphology, structure and crystalline phase, as well as other factors. Besides, the reaction mechanisms for catalytic oxidation of for-maldehyde over some manganese oxides catalysts have also been summarized. It is indicated that future research of manganese oxides catalysts with high efficiency, economy and environmentally benign on ox-idation of HCHO should be improved the catalytic performance by increasing the number of active sites, constructing more defects, adding additives and doping modification.
