摘要
采用共沉降法制备了以Ni为载体的NiCo2O4/Ni的电催化剂,分别用TG、XRD、SEM对NiCo2O4粉末的结构和形貌进行了表征,研究了不同温度下NiCo2O4/Ni复合电极在碱性水溶液中的催化性能。结果表明,热处理温度对NiCo2O4粉末的结构、电催化性能有重要的影响,当热处理温度为300℃时NiCo2O4/Ni复合电极的电催化性能最好。
NiCo2O4 electro-catalysis with Ni was prepared as a substrate through the hydroxide coprecipitation method.The structure and microstructure morphology of NiCo2O4 powders were analyzed by TG,XRD,and SEM,respectively.The catalytic properties of NiCo2O4/Ni combination electrode were investigated under the condition of alkaline solution at the different measured temperatures.It turned out that the heat-treatment temperature had a significant effect on of the composition and electrocatalytic properities of NiCo2O4 powders.And NiCo2O4/Ni composited electrode has the best electrocatalytic properities when prepared at 300℃.
