The invention provides a molecular sieve coating load manganese based composite oxide integrated catalyst with easy material acquisition, low preparation cost and firm combination of active constituents and carrier of catalyst, and a preparation method thereof for the defects that the noble metal catalyst has few noble metal resources, high price and high preparation cost. The catalyst provided by the invention is a cellular catalytic combustion catalyst, which comprises a molecular sieve coating, a manganese based composite oxide and a cellular carrier. The catalyst provided by the invention is prepared by the following steps of: uniformly mixing a precursor with the manganese based composite oxide, the molecular sieve and the water to obtain a grout with manganese based composite oxide precursor; soaking the cellular carrier into the grout with manganese based composite oxide precursor; and drying and baking to obtain the molecular sieve coating load manganese based composite oxide integrated catalyst.
