▎ 摘　　要

NOVELTY - Preparation of graphene oxide/nano gold particle composite material comprises extracting graphene oxide to process acylation reaction for obtained graphene oxide; reacting graphene oxide with chloroauric acid; adjusting pH value; and filtering sediment to obtain graphene oxide/nano gold particle composite material. USE - Preparation of graphene oxide/nano gold particle composite material. ADVANTAGE - The method is simple, provides high yield, large output, and good quality product. It solves problem that current method for preparing graphene oxide/nano gold particle composite material with monatomic thickness is complex and needs special apparatus. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a process for preparing graphene oxide/nano gold particle composite material (Drawing includes non-English language text).
