电沉积制备Ni-Fe/TiO_2复合电极及其析氢催化性能
|
摘要
通过电沉积的方法制备了Ni-Fe/TiO_2复合电极,采用阴极极化曲线和电化学阻抗谱的方法对电极的析氢催化性能进行了分析。结果表明:Ni-Fe/TiO_2复合电极的析氢催化性能优于Ni-Fe合金电极,TiO_2微粒作为第二相粒子可以增大电极的比表面积;Ti原子可以与H形成Ti-H_(ads)氢键,加快H_(ads)生成;TiO_2微粒可与Ni-Fe合金形成H_(ads)的复合脱附效应,使电极的析氢催化性能得到提高。随着镀液中TiO_2微粒添加量的增大,电极的析氢催化性能先增强后减弱。
Ni-Fe/TiO_2 composite electrodes were prepared by electrodeposition.Cathodic polarization curve and electrochemical impedance spectroscopy were used to study the hydrogen catalytic property of electrodes.The results show that the hydrogen evolution property of Ni-Fe/TiO_2 composite electrode is better than Ni-Fe alloy electrode.TiO_2 particles can increase specific surface area of electrode,Ti can form Ti-H_(ads) hydrogen bond with H,which is favorable for formation and adsorption,a composite desorption effect of H_(ads) exists between TiO_2 particles and Ni-Fe alloy,enhancing hydrogen catalytic performance of electrode.With the addition of TiO_2 particles in the bath,the catalytic performance for hydrogen evolution of electrode first increases and then weakens.
