▎ 摘　　要

NOVELTY - Preparing three-dimensional porous graphene-encapsulated nano-zero-valent copper complex material comprises (i) mixing graphene oxide with potassium bromohydride at room temperature, dropping copper sulfate pentahydrate solution into a mixture of graphene oxide and potassium bromohydride in an oxygen-free atmosphere, reacting, precipitating the synthesized complex material naturally, removing the supernatant, washing with ultrapure water or a mixture of hydrochloric acid and ultrapure water and subjecting the washed sample to freeze vacuum drying. USE - The method is useful for preparing three-dimensional porous graphene-encapsulated nano-zero-valent copper complex material. ADVANTAGE - The method has mild reaction conditions, is simple and economical.
