摘    要
通过水热法制备了CeO2-MnO2纳米氧化物/石墨烯复合电极材料,采用扫描电镜、透射电镜、X射线衍射仪、拉曼光谱仪等对复合电极材料的表面形貌、晶体结构, 石墨烯表面官能团等进行了研究; 并用恒流充放电、循环伏安法研究了复合电极材料的电化学性能。结果表明: 氧化铈的掺入对电极循环次数的提高有着明显的促进作用; 在铈锰物质的量比为2∶8时, 复合电极材料的比电容和电容损达到最优, 在10 mV·s-1扫描速度下, 1 mol·L-1的Na2SO4电解液里测试的比电容最大达到157 F·g-1, 且充放电1 000次循环后, 电容损低至23 %。

Abstract
CeO2-MnO2 nano-oxide/graphene composite electrode materials were prepared by hydrothermal method. The morphology, crystal structure of composite electrode materials and functional group on the surface graphene were investigated by SEM, TEM, XRD and Raman microscopy. And the electrochemical performance of the composite electrode materials was also studied using constant current charging-discharging and cyclic voltammetry (CV). The results indicate that the addition of CeO2 could improve cycle number on electrode cycles. When the mole ratio of cerium to manganese was 2∶8, the best specific capacitance with maximum value of 157 F·g-1 under the scanning speed of 10 mV·s–1 in 1 mol·L-1 Na2SO4 electrolyte, and capacitance loss of 23% after 1 000 cycles of charging and discharging were achieved.
