| 摘要: 以六水合硝酸钴[Co（NO3）2·6H2O]为钴源、六水合硝酸锌[Zn（NO3）2·6H2O]为锌源、2，2'-硫代二乙酸（C4H6O4S）为硫源，采用溶剂热法制备出了片状的Co9S8/ZnS/C复合材料。采用X射线衍射（XRD）、扫描电镜（SEM）、透射电镜（TEM）和N2吸附/脱附测试等手段对于片状Co9S8/ZnS/C复合材料结构和形貌等进行表征，同时对片状Co9S8/ZnS/C复合材料进行了电催化产氧性能测试。结果表明：片状Co9S8/ZnS/C复合材料的起始过电位为390 mV，塔菲尔斜率为144 mV·dec-1，具有高的电催化产氧性能。 |

| Abstract: The flake Co9S8/ZnS/C composites were prepared by solvothermal method, through using cobalt hexahydrate[Co(NO3)2·6H2O] as cobalt source, zinc hexahydrate nitrate[Zn(NO3)2·6H2O] as zinc source and 2,2'-thiodiacetic acid (C4H6O4S) as sulfur source. The flake Co9S8/ZnS/C composites structure and morphology were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption test. Meanwhile, the results of electrocatalytic oxygen evolution reaction for the flake Co9S8/ZnS/C composite showed that it had high electrocatalytic oxygen production performance, with the initial overpotential of 390 mV and the Tafel slope of 144 mV·dec-1. |
