采用氢氧化物共沉淀法制备了NiCo 2 O 4尖晶石氧化物。采用TGA、XRD、BET、SEM和EDS等手段对NiCo 2 O 4粉体进行了分析。通过循环伏安法、粗糙因子法、Tafel曲线法和稳定性测试，评价了NiCo 2 O 4/Ni电极在碱性溶液中析氧的电催化性能。结果表明，制备温度对NiCo 2 O 4尖晶石氧化物的形成、比表面积、形貌和电催化性能均有影响。在300 ℃下制备的NiCo_2O_4/Ni电极具有较好的析氧电催化性能。(C)2003年国际氢能协会。由爱思唯尔有限公司出版。保留所有权利。
NiCo2O4 spinel oxide was prepared through the hydroxide coprecipitation method. The NiCo2O4 powders were analyzed by TGA, XRD, BET, SEM, and EDS. And the electrocatalytic properties of NiCo2O4/Ni electrode for oxygen evolution in alkaline solution were evaluated by cyclic voltammetry, roughness factor, Tafel curves and stability testing. The result shows that the preparation temperature can affect the formation, specific surface area, morphologies, and electrocatalytic properties of NiCo2O4 spinel oxide. It is also found that NiCo2O4/Ni electrode prepared at 300degreesC has better electrocatalytic properties in oxygen evolution reaction than those prepared at other temperatures.
