| 摘 要： | 在贱金属铁基表面化学镀Ｎｉ－Ｃｏ－Ｐ，然后通过化学复合镀制得Ｎｉ－Ｃｏ－Ｐ－Ａ１２Ｏ３底层，复合镀层用ＮａＯＨ溶液浸出，可制得新型Ｎｉ－Ｃｏ－Ｐ微孔活性中间导参中间导地涂覆匹配性较好的ＮｉＣｏ２Ｏ４表面活性层，该表面活性层由一定浓度配比的Ｎｉ（ＮＯ３）２和Ｃｏ（ＮＯ３）２通过高温热解而成。 射结果表明表面活性层是由ＮｉＣｏ２Ｏ４组成，不存在ＮｉＯ和Ｃｏ３Ｏ４的独立相。这种新型表面活性层用于碱性水电

| Abstract: | Electroless plating Ni Co P and composite electroless plating Ni Co P Al 2O 3 subsequently on Fe substrate were presented. After Ni Co P Al 2O 3 coatings immersed in 5 mol/L NaOH solution, a new micro hole and active coating was formed. Deposition of the active NiCo 2O 4 coating on surface of Ni Co P coating was formed after heat treatment in 2.0 mol/L Ni(NO 3) 2 CO(NO 3) 2 mixing solutions at high temperature. Composition of the surface coating (NiCo 2O 4) was verified by X ray diffraction analysis, which showed that no NiO and Co 3O 4 existed. The new DSA for alkaline water electrolysis has higher catalytic activity and longer life time. |
