以碳纳米管（CNTs）为载体，通过调控水热反应时间及温度负载NiCo颗粒，制备NiCo/CNTs复合催化剂。利用碳纳米管独特的中空管状结构、高比表面积以及良好的导电特性来负载高活性的NiCo颗粒，开发高性能析氧催化剂。利用激光拉曼、扫描电子显微镜、X射线衍射和电化学测试研究了水热反应温度与时间对NiCo/CNTs复合催化剂形貌、晶型结构及电化学性能的影响。结果表明，在130℃、24 h与150℃、8 h条件下制备的NiCo/CNTs复合催化剂的综合性能较为优异。

Carbon nanotubes, with unique hollow tubular structure, high specific surface area and good electrical conductivity, are used to load NiCo particles with high activity to develop high performance oxygen evolution catalysts.NiCo/CNTs composite catalyst is prepared by loading NiCo particles on carbon nanotubes (CNTs) through regulating the time and temperature of hydrothermal reaction.Raman laser, scanning electron microscope (SEM), X-ray diffraction (XRD) and electrochemical test are employed to study the influences of reaction temperature and time on the morphology, crystal structure and electrochemical performance of NiCo/CNTs composite catalyst.It is shown that NiCo/CNTs composite catalysts prepared at 130℃ for 24 h and 150℃ for 8 h have better overall performance.
