摘要
采用在化学法制备Ni(OH) 2 过程中用共沉积的方法掺加添加剂 ,用排水取气法、循环伏安法研究了各种添加剂对镍电极析氧过程的影响 ,通过对十几种添加剂的考察 ,认为Sr(OH) 2 ,Co(OH) 2 和La(OH) 3 对降低析氧速率。
Chemical co_deposited method was used to append additive agent to Ni(OH) 2 in process of preparation of Ni(OH) 2. The effects of addition agent on the oxygen evolution process were investigated by cyclic voltammetry method and collecting gas by draining water method. The result shows that Sr(OH) 2,Co(OH) 2 and La(OH) 3 are the three of addition agents that have excellent effects on decreasing velocity of oxygen evolution and increasing charge efficiency.
