▎ 摘　　要

NOVELTY - Preparing sandwich graphene aerogel-based catalyst filter material involves adsorbing chlorine-doped graphene oxide aerogel (ClAGO) on the surface of the polyphenylene sulfide filter material through a condensation reaction to form an intermediate layer. A binary manganese cerium oxide (Mn-CeOx) catalyst is grown in situ on the middle layer as the outermost layer to obtain the sandwich graphene aerogel-based catalyst filter material. USE - Method for preparing sandwich graphene aerogel-based catalyst filter material. ADVANTAGE - The method uses potassium permanganate as the oxidant to generate redox reactions on the surface of the chlorine-doped graphene aerogel, so that the manganese-cerium oxide catalyst is grown in situ on the surface of the chlorine-doped graphene aerogel. The outermost catalyst layer is formed, and finally a composite denitration and anti-sulfur filter material loaded with interlayered chlorine-doped graphene aerogel is prepared.
