▎ 摘　　要

The composite of carbon nanotubes/graphene networks loaded-Ni (CNTs/GR-Ni) were successfully synthesized by spray drying and post-calcinating method for the first time. The synthesized products were systematically studied by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The result showed the hybrid of CNTs and graphene composed the 3D network structure and Ni nanoparticles were attaching on their surface. Adsorption performance evidenced that the obtained nanocomposite possessed high adsorption efficiency and excellent separation property.
