▎ 摘　　要

NOVELTY - Polyphenylene sulfide (PPS) composite material of insitu loaded sulfur-doped graphene catalyst, prepared by adopting activated PPS fiber in-situ grown sulfur-doped graphene as catalyst carrier, and loading the modified PPS fiber with ternary manganese-cerium- palladium oxide (Mn-Ce-PdOx) catalyst to obtain the composite material. USE - The catalyst is useful in denitration with anti-sulfur function (claimed). ADVANTAGE - The catalyst has high performance denitration and anti-sulfur function on the surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the PPS composite material of in-situ loaded sulfur-doped graphene catalyst, comprising (A) adding a piece of S-rGO-PPS into a 250 ml beaker with 100 ml deionized water, ultrasonically processing for 15 minutes, adding 0.06 g sodium dodecyl sulfate, placing in a rotor and then in 60 degrees C water bath and stirring for 30 minutes, (B) heating the water bath to 85 degrees C, adding cerium nitrate hexahydrate to the prepared solution, stirring for 1 hour to completely dissolve, simultaneously grafting cerium (III) to the S-rGO-PPS surface by electrostatic interaction, (C) adding palladium chloride into the solution, completely dissolving palladium chloride, continuously stirring for 1 hour in a water bath of 85 degrees C, simultaneously filling S-rGO-PPS surface with palladium (II) and cerium (III) reaction product, and (D) preparing potassium permanganate solution, adding to the solution in the step (C), maintaining the reaction temperature and continuously reacting for 2 hours, taking S-rGO-PPS filter, cleaning with deionized water and drying to obtain the in-situ loaded sulfur-doped graphene PPS denitration and anti-sulfur function filter material as manganese-cerium-palladium oxide/S-rGO-PPS.
