摘要：

In this paper, three-dimensional graphene (3DG) electrode material was prepared by hydrothermal reduction using graphene oxide as precursor. Its morphology and structure were characterized by SEM, BET, XRD, Raman, FTIR and TG, and its electrochemical performance was also measured. The results showed that 3DG possessed hierarchical pore structure, large specific surface area, high specific capacitance and low impedance. Using 3DG as electrode material for electrosorption of UO22+, it showed that the saturated adsorption capacity can reach up to 113.80 mg g(-1) and the adsorption rate is 0.32 mg g(-1) min(-1) at a given optimal applied voltage of 1.8 V.
