摘要

通过电化学阳极氧化和电化学沉积相结合的方法制备了TiO₂纳米管阵列/磷化钴复合纳米电极(TiO₂NTs/CoP)。采用X射线衍射仪(XRD)和场发射扫描电子显微镜(FESEM)对复合电极的结构和形貌进行了表征,并利用极化曲线技术测试了其在1mol/L KOH溶液中对电解水析氢反应(HER)和析氧反应(OER)的催化性能。结果表明:在电催化析氢和析氧反应中,该电极在10mA/cm²电流密度下的过电位分别112mV和320mV,与其他电极相比具有良好的电催化活性,可以作为电解水反应的双功能电催化剂。

Abstract

TiO₂NTs/CoP nanocomposite electrode was successfully prepared by combination of electrochemical anodization and electrodeposition.The structure and morphology of the composite electrode were characterized by X-ray diffractometer (XRD) and field emission scanning electron microscope (FESEM).The electrocatalytic performance of the composite electrode for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in 1mol/L KOH solution was tested by polarization curve technique.The results indicated that the overpotential of the TiO₂NT_S/CoP was 112mV for HER and 320mV for OER at the current density of 10mA·cm^-2,respectively.Compared with other electrodes,the TiO₂NT_S/CoP had good electrocatalytic performance,and could be used as bifunctional electrocatalyst for water electrolysis.
