| 英文摘要 | The chemical vapor deposition (CVD) fabrication of high-density three-dimension graphene macroscopic objects (3D-GMOs) with a relatively low porosity has not yet been realized, although they are desirable for applications in which high mechanical and electrical properties are required. Here, we explore a method to rapidly prepare the high-density 3D-GMOs using nickel chloride hexahydrate (NiCl2 center dot 6H(2)O) as a catalyst precursor by CVD process at atmospheric pressure. Further, the free-standing 3D-GMOs are employed as electrolytic electrodes to remove various heavy metal ions. The robust 3D structure, high conductivity (similar to 12 S/cm) and large specific surface area (similar to 560 m(2)/g) enable ultra-high electrical adsorption capacities (Cd2+ similar to 434 mg/g, Pb2+ similar to 882 mg/g, Ni2+ similar to 1,683 mg/g, Cu2+ similar to 3,820 mg/g) from aqueous solutions and fast desorption. The current work has significance in the studies of both the fabrication of high-density 3D-GMOs and the removal of heavy metal ions. |
