| 摘 要： | 采用直流电镀技术,通过改变电沉积电流密度制备了不同的非晶Ni-Fe-P涂层。采用稳态极化技术比较不同电流密度下电镀Ni-Fe-P合金涂层电化学催化析氢活性,发现电流密度200A/m2电沉积的Ni-Fe-P合金涂层的电化学催化析氢性能最好。通过XRD分析镀层相结构,SEM观察涂层表面的微观结构及EDX分析表面成分,研究影响非晶Ni-Fe-P合金涂层的析氢电催化活性原因。结果表明,影响非晶Ni-Fe-P合金涂层电催化活性的主要因素是镀层中Fe、P元素含量。当Fe的含量最大18.63%(原子分数),P的含量最小13.14%(原子分数)时,非晶Ni-Fe-P涂层电催化析氢活性最好。2

| Abstract: | The different amorphous Ni-Fe-P coatings have been prepared with direct current plating technology through changing the current density.Catalytic activity of those electrodes prepared for hydrogen evolution reaction(HER) was compared with the steady-state polarization technique.Results indicated that Ni-Fe-P coating prepared at current density of 200A/m2 shows much better catalytic activity.Surface morphology and elemental composition of the coatings were investigated by scanning electron microscopy(SEM) an... |
