活性炭负载镍析氢电催化剂的制备和表征

摘要采用化学还原法制备了以椰壳活性炭(AC)为载体的Ni/AC电催化剂。运用SEM和XRD对Ni/AC电催化剂的形貌和结构进行了分析。研究了镍负载量、制备温度和还原剂N2H4与Ni2+的摩尔比对Ni/AC电催化剂析氢催化活性的影响。结果表明,负载在活性炭上的镍为面心立方晶系,其镍的负载量、制备温度和N2H4(还原剂)/Ni2+摩尔比对Ni/AC电催化剂的析氢催化活性有显著的影响。

Abstract： The Ni/active carbon(AC) electro-catalyst was prepared by chemical reduction method using coconut carbon as the support.Morphologies and structures of Ni/AC were measured and characterized by X-ray diffraction and scanning electron microscopy.The factors of performance on Ni/AC electro-catalyst were studied.The results showed that Ni content,reaction temperature and mole ratio of N_2H_4/Ni~(2+) had the main effect on performance of Ni/AC electro-catalyst for hydrogen evolution.
