NOVELTY - The method involves adding graphene oxide, chlorine-free nitrogen-containing platinum precursor tetraaamineplatinum hydroxide, copper precursor, protective agent and sodium citrate to water in a predetermined proportion to obtain a mixed solution. The mixed solution is transferred to an autoclave for hydrothermal reduction, filtered and dried to obtain catalyst powder. The sum of the moles of copper and platinum is defined as M, and the moles of sodium citrate as N. The ratio of N to M is 1-10:1. The copper precursor is copper nitrate. The protective agent is polyethylene glycol (PEG). USE - Method for preparing N-reducing graphene oxide supported platinum copper alloy nanocatalyst. ADVANTAGE - The method is configured to use non-chlorine-containing platinum precursor, which effectively avoid the existing technology caused by using chloroplatinic acid, chloroplatternic acid potassium and other chlorine-containing precursor caused by chlorine poisoning phenomenon. Platinum precursor is provided with nitrogen source, and is configured to skillfully introduce the nitrogen source and does not need to introduce other nitrogen-containing organic as nitrogen source. The method is simple, and is configured to effectively avoid the complex side reaction. The precursor has positive electricity, good water-solubility, easy to generate electrostatic adsorption effect with the oxygen-containing functional group with negative electricity on reducing graphene oxide (rGO). The precursor is uniformly absorbed on the surface of the carrier, which is good for uniformly anchoring the platinum-based alloy nano-particles on surface of carrier, obtaining nano particles with DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the process of preparing platinum copper alloy nano catalyst.
