NOVELTY - A modified graphene catalytic slurry comprises 4000-90000 pts. wt. solvent, 20-200 pts. wt. dispersant, 500-3000 pts. wt. binder, 0-1000 pts. wt. additive and 1000-3000 pts. wt. modified graphene. The solvent is water, dimethylformamide, N-methylpyrrolidone and dimethylacetamide. The dispersant is polyvinylpyrrolidone, sodium dodecylsulfonate and polyvinyl alcohol. The binder is sodium carboxymethylcellulose, hydroxypropylmethylcellulose, polytetrafluoroethylene, polyvinylidene fluoride, polyvinyl alcohol and styrene-butadiene rubber. The additive is adsorbed carbon material with BET specific surface area of 1200 m2/g. The modified graphene is rich in edge, pore structure, five-membered ring, seven-membered ring and hetero atom. USE - A modified graphene catalytic slurry. ADVANTAGE - The product is low-cost, has viscosity of 3500-6500 mPa Pa.s, has simple preparation, has high catalytic activity, suitable for water body treatment, energy efficient and environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of modified graphene catalytic slurry comprising: (A) utilizing water as solvent, dividing binder iinto first binder and second binder; first binder comprises sodium carboxymethyl cellulose or hydroxypropyl methylcellulose; and second binder comprises polytetrafluoroethylene, polyvinylidene fluoride, polyvinyl alcohol and styrene-butadiene rubber, mixing 70000-90000 pts. wt. water, 150-250 pts. wt. first binder and 20-100 pts. wt. dispersant, stirring to obtain first intermediate product, mixing with 2500-3000 pts. wt. modified graphene, stirring to obtain second intermediate product, and mixing and stirring with 1700-2200 pts. wt. second binder; and (B) utilizing dimethylformamide as solvent, mixing 40000-60000 pts. wt. dimethylformamide and 80-120 pts. wt. dispersant, stirring to obtain first product, mixing with 1200-1300 pts. wt. binder, stirring to obtain second product, mixing with 1300-1700 pts. wt. modified graphene, and stirring.
