NOVELTY - Preparing iron-nickel complex as precursor, graphene oxide as template of the electrocatalyst involves 5.5mL containing nickel chlorate compound ((Ni(L)(H2O)2)(ClO4)2) where Ni is 2, 6, L is 2, 12-dimethyl-3, 7, 11, 17- tetra-aza-bicyclo(11.3.1) heptaheptylbicyclo (17), 2, 11, 13, 15-pentaene, (76.7mg, 0.15 mmol) of acetonitrile (CH3CN) solution, adding to 5 mL potassium ferrocyanide (K3(Fe(CN)6)) (32.9mg, 0.10 mmol) of water solution, adding nickel(II) chloride hexahydrate (NiCl6.6H2O) (0.02mmol, 7.59mg) into the suspension, stirring for half an hour, solution aging overnight, filtering to obtain iron nickel precipitate (FeNi-CP), washing with acetonitrile, drying in the air, using ultrasonic bath to pre-treat 30 mg of oxidized graphene (GO) in 40 mL of ethanol. USE - Method for preparing iron-nickel complex as precursor, graphene oxide as template of electrocatalyst. ADVANTAGE - The method has excellent electro-catalysis performance, and shows good stability and activity on the zinc-air battery.
