The invention provides a catalyst for low-temperature catalytic combustion, a preparation method and application thereof, wherein the catalyst is prepared from a composite oxide Ce of cerium (Ce) and manganese (Mn) x Mn y O z A catalyst in the form of a solid powder; wherein x = 2-20, y = 1-2, and z = 4-44; the catalyst is prepared by a sol-gel method, a coprecipitation method or a hydrothermal method. The catalyst can efficiently remove aromatic volatile organic compounds, has high low-temperature catalytic combustion activity, and the manganese-cerium composite metal oxide catalyst prepared by the sol-gel method has higher low-temperature catalysis on reactantsThe activity of chemical combustion; when the conversion rate of reactant benzene is 90%, the reaction temperature is reduced to 302 ℃, and the method has wide application prospect and good economic benefit. |
