▎ 摘　　要

NOVELTY - The method involves adding 80-140 mg of graphene water solution in 0.5-2 mmol of a liquid phase metal source. Reducing agent is added with liquid phase metal source. Constant temperature water bath ultrasonic wave is obtained in a container. Drying process is carried out by a precipitate product to prepare a graphene sheet single/multi-loading noble metal nano particle. The liquid phase metal source is filled with chloroauric acid, palladium acetate and silver ammonia solution. The reducing agent is mixed with sodium borohydride, ascorbic acid, glucose and ammonium citric acid. USE - Graphene sheet single/multi-loading metal nano particle preparing method. ADVANTAGE - The method enables reducing preparing cost of a sheet-like graphene composite material, thus improving repeatability of the sheet-like graphene composite material. The method enables ensuring parameter adjustable range of the sheet-like graphene composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a graphene sheet single/multi-loading metal nano particle.
