| 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. |
