摘要:
采用电沉积法在碳化硅纳米线薄膜上沉积镍硫合金，制备碳化硅纳米线/镍硫合金薄膜复合电极，采用场发射扫描电子显微镜(FESEM)、X射线衍射(XRD)、阴极极化曲线(LSV)等分析测试方法对该薄膜的形貌、结构和电化学性能进行了表征。结果表明：镍硫合金沉积层主要以Ni-3S-2结晶态的形式覆盖在碳化硅纳米线薄膜表面，纳米线沉积合金前直径约80 nm，沉积后增大到100 nm左右。重点研究了Ni-3S-2/SiC 电极在光照前后的光电性能，在1 M KOH 溶液中的LSV曲线测试表明：Ni-3S-2/SiC电极的起始电压比SiC电极减小约200mV；在光照下Ni-3S-2/SiC电极起始电压比无光照下降低约 400 mV(电流密度为9 mA·cm 2)，计时电位曲线测试表明电极具有很好的稳定性。
