Abstract

The novel 3D graphene oxide/multi-walled carbon nanotubes/ZnO nanocrystalline aggregate (GR/MWNTs/ZnO) hybrids were prepared by a spray drying method, and their adsorption and photocatalytic degradation for methyl orange (MO) were studied. Experimental results show that the synthetic GR/MWNTs/ZnO nanohybrids exhibited very strong adsorption capacity and high photocatalytic activity for MO. The maximum adsorption capacity of GR/MWNTs/ZnO sample reached 106.2 mg/g, and the photocatalytic efficiency of ZnO nanocrystallines was improved about one time by GR/MWNTs hybrids.
