▎ 摘　　要

NOVELTY - Nitrogen-reduced graphene oxide supported copper-nickel bimetallic monoatomic catalyst comprises a carrier nitrogen-reduced graphene oxide and a metal species supported on the carrier, the metal species including copper and nickel, and the radius of the metal species is less than 2 angstrom. USE - Nitrogen-reduced graphene oxide supported copper-nickel bimetallic monoatomic catalyst used as a desulfurization catalyst to catalyze the selective C-S bond cleavage reaction of sulfide in fuel (claimed). ADVANTAGE - The nitrogen-reduced graphene oxide supported copper-nickel bimetallic monoatomic catalyst has high catalyst activity and simple to process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an N-rGO-supported copper-nickel bimetallic monoatomic catalyst, which involves: (A) mixing graphene with hydrochloric acid and adding aniline to obtain a first suspension; (B) adding (NH4) 2S2O8 solution to the first suspension, and then mixing, filtering, drying, and baking in order to obtain N-rGO; (C) adding N-rGO to water and adding Na2CO3 solution to obtain a second suspension; (D) mixing mixed aqueous solution of copper nitrate and nickel nitrate and an aqueous solution of polyvinyl alcohol together to obtain a mixed solution; and (E) adding mixed liquid to the second suspension liquid, after mixing, filtering, drying, and baking in order to obtain N-rGO-supported copper-nickel bimetal monoatomic catalyst.
