| 摘 要： | Ni-W-P合金薄膜具有优良的催化析氢性能和耐蚀性.通过在半导体p型Si上恒电流沉积Ni-W-P合金薄膜,制备出Ni-W-P合金修饰的半导体p型Si电极.用SEM和XRD对合金薄膜的表面形貌、组成和结构进行了表征,以电极的阴极极化曲线对其催化析氢和光电催化析氢性能进行评价.结果表明:W,P质量分数分别为26.71%和0.95%的纳米晶合金修饰的p型Si电极具有优良的催化析氢性能和显著的光电析氢活性.

| Abstract: | Ni-W-P/p-Si electrode was prepared by constant current electrodepositing Ni-W-P alloy film on p-Si. The surface morphology, chemical composition and structure of alloy film were characterized by using SEM and XRD, and its catalytic/photoelectrocatalytic property for hydrogen evolution reaction (HER) were evaluated by cathodic polarization curves. Results show that the nanocrystalline Ni-W-P/p-Si electrode containing 26.71% W and 0.95% P in wt% exhibits a high catalytic activity and great photoelectrocatalysis property for HER. |
