▎ 摘　　要

NOVELTY - A graphene-hollow copper nanosphere composite material is prepared by evenly loading hollow copper nanospheres on the surface of graphene. USE - The graphene-hollow copper nanosphere composite material is useful as a catalyst in the reduction and hydrogenation of p-nitrophenol to prepare p-aminophenol (claimed). ADVANTAGE - The graphene-hollow copper nanosphere composite material has high catalytic kinetic constant compared with traditional copper-based catalyst. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing the graphene-hollow copper nanosphere composite material, which involves (1) dispersing graphene oxide prepared by modified Hummers method in a first portion of ethylene glycol to form a solution (A), (2) dissolving a copper salt in a second portion of ethylene glycol to form a metal precursor solution (B), and (3) mixing the solution (A) and the metal precursor solution (B) to obtain a mixed solution (C), heating, washing and drying the heated product; and (2) use of the graphene-hollow copper nanosphere composite material in the reduction and hydrogenation of p-nitrophenol to prepare p-aminophenol, which plays a catalytic role in the reduction and hydrogenation of p-nitrophenol to p-aminophenol, where the reduction step is performed by using a reducing agent of sodium borohydride, and the dosage ratio of p-nitrophenol to catalyst is 1 mmol:(10-80) mg, preferably 1 mmol:50 mg.
