▎ 摘　　要

NOVELTY - Preparing nitrogen-doped reduced graphene oxide supported manganese nanoparticle catalyst comprises (i) dispersing graphene oxide in an alcohol-water mixed solvent to obtain a graphene oxide suspension; (ii) adding polyethylene glycol, water-soluble manganese salt and organic nitrogen source to the graphene oxide suspension, and adjusting the pH of the resulting mixed solution to alkaline; (iii) placing the mixed solution in an autoclave, cooling, washing, hydrothermally reacting, and drying to obtain a solid mixture of nano-manganese oxide precursor and nitrogen-doped reduced graphene oxide; and (iv) heat treating solid mixture in an inert atmosphere of 800-1200℃ for a predetermined time. The manganese salt is manganese acetate, and the organic nitrogen source is dimeric cyanamide. USE - The method is useful for preparing nitrogen-doped reduced graphene oxide supported manganese nanoparticle catalyst. ADVANTAGE - The catalyst has good catalytic activity, stability and methanol resistance. DESCRIPTION OF DRAWING(S) - The diagram shows a flowchart of the method for preparing nitrogen-doped reduced graphene oxide supported manganese nanoparticle catalyst (Drawing includes non-English language text).
