Monolithic nitric oxide low-temperature oxidation catalyst and preparation method thereof

The invention discloses a monolithic nitric oxide low-temperature oxidation catalyst and a preparation method thereof. The monolithic nanocarbon loaded manganese-lanthanum oxide catalyst is composed of monolithic nanocarbon and manganese-lanthanum oxide, the monolithic nanocarbon is composed of a carbon felt and nanocarbon fibers, and the manganese-lanthanum oxide consists of manganese oxide and lanthanum oxide; the manganese-lanthanum oxide is 5-60wt% relative to the total weight of the monolithic nanocarbon loaded manganese-lanthanum oxide catalyst, and the molar ratio of manganese to lanthanum is 1:0.05-2.
