NOVELTY - The method involves taking chloroauric acid, oxidized graphite alkene and sodium citrate in an oil bath, and heating and stirring mixture. A gold nanometer particle/graphene oxide composite material is washed by uniformly dispersing the mixture in water. A gold nanometer particle/graphene oxide composite material film is dried by vacuum filtering process. The dried gold nanometer particle/graphene oxide composite material film is crushed, and exposed to air. The film is heated to obtain a porous metal film. USE - Method for preparing nanometer-sized porous gold thin film material using graphene. ADVANTAGE - The method enables achieving simple operation with mild preparation condition and non-toxic and environment-friendly environment, and controlling shape of the nano-porous metal film in effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view illustrating a method for preparing nanometer-sized porous gold thin film material.
