Cu-Ce doped type manganese oxide catalyst, preparation method and application thereof

The invention discloses a Cu-Ce doped type manganese oxide catalyst, a preparation method and the application of the Cu-Ce doped type manganese oxide catalyst. The precursor Birnessite-type manganese oxide of the catalyst is firstly prepared by a sol-gel method, the components Ce and Cu are introduced at the same time by an immersion method, and finally, the Cu-Ce doped type manganese oxide catalyst can be obtained by roasting. The Cu-Ce doped type manganese oxide catalyst is low in price, has better adaptability, can be applied to the catalytic combustion of dimethyl ether and volatile organic compounds (VOCs), has excellent low-temperature activity, and only has the products of carbon dioxide and water without other by-products.
