Abstract

In this paper, graphene/multi-walled carbon nanotubes (GM) hybrid nanostructure was synthesized by modifying GR using salicylamide. Cu-doped ZnO nanoparticles were successfully decorated on GR/MWNTs hybrids (GM). Their photocatalytic performance for the degradation of methyl orange (MO) was investigated and the results showed that the synthetic GM/Cu-doped ZnO hybrids exhibited better photocatalytic ability than MWNTs/Cu-doped ZnO and GR/Cu-doped ZnO hybrids, in which the degraded rate for 20 mg/L MO solution reaches about 100% in 45 min.
