摘　　要：通过温度调变,原位电解制备Co-C_i析氧催化剂,70℃条件下所制备催化剂具有微纳米颗粒形貌,其析氧催化性能最佳,析氧速率为29.5μmol/h,电流密度为1 m A/cm^2时析氧过电位为212 mV。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、X射线能谱(EDS)、X射线光电子能谱(XPS)表征方法对其形貌、结构及组成进行分析,通过电化学方法考察其析氧催化性能和稳定性能。The Co-Ci oxygen-evolution catalysts were prepared in situ by modulation of temperature. The catalyst prepared at the temperature of 70 ℃ has micro-nano structure and better electrochemical properties. The oxygen- evolution rate of Co-Ci was 29.5 μmol/h and the overpotential was 212 mV at the current density of 1 mA/cm2. The structure, morphology, and composition of Co-C/catalysts were investigated by XRD, SEM, EDS, and XPS. The oxygen- evolution performance and stability were carried out by electrochemical means.
