The invention discloses a nitrogen-sulfur co-doped graphene composite material (marked as Mn-Ce-SnOx/rGO-N,S) supporting a ternary high-efficiency denitration and sulfur-resistant catalyst and a preparation method thereof. After in-situ growth of an efficient denitration and anti-sulfur ternary catalyst on heterographene oxide, nitrogen-sulfur co-doping is performed and graphene oxide is reduced to obtain a nitrogen-sulfur co-doped graphene catalyst composite material. Due to the in-situ growth method, the three-way catalyst is uniformly and firmly loaded on the surface of nitrogen-sulfur co-doped graphene; the overall synthesis of the present invention is carried out in a low temperature environment, the reaction synthesis method and operation are very simple, and the reaction is fast. , there is no specific requirement for the reaction vessel, and the synthetic material does not pollute the environment, the synthesized catalyst and the nitrogen-sulfur co-doped graphene are firmly bonded, the service life is long, and the out-of-stock rate is high. |
