| 摘 要： | 以六水合硝酸钴Co(NO_3)_2·6H_2O]为钴源、六水合硝酸锌Zn(NO_3)_2·6H_2O]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Co_9S_8/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N_2吸附/脱附测试等手段对于片状Co_9S_8/ZnS/C复合材料结构和形貌等进行表征,同时对片状Co_9S_8/ZnS/C复合材料进行了电催化产氧性能测试。结果表明:片状Co_9S_8/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 hexahydrateCo(NO3)2·6H2O] as cobalt source, zinc hexahydrate nitrateZn(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. |
