NOVELTY - Preparation of low temperature selective catalytic reduction activity modified filter material comprising using sol-gel method to prepare zirconium-manganese-iron oxide loaded on reduced graphene oxide catalyst and using sodium dodecylbenzene sulfonate as surfactant to combine catalyst and polyphenylene sulfide fiber. USE - The method is used for preparing low temperature selective catalytic reduction activity modified filter material. ADVANTAGE - The introduced graphene filter material has high specific surface area, provides abundant active oxygen species and acid sites, and has more surface chemisorption oxygen and low-valence manganese oxide.
