The properties of hydrogen evolution of AuPdPt-WC/C nano composite catalyst in simulated seawater solution

为探究电解海水析氢,采用直接还原法制备WC促进的AuPdPt-WC/C复合催化剂。首次在模拟海水条件下测试AuPdPt-WC/C催化剂析氢性能表明其有良好的催化活性。阴极极化曲线表明AuPdPtWC/C催化剂比商业Pt/C催化剂具有更正的析氢过电位和更大的去极化能力。AuPdPt-WC/C催化剂在模拟海水溶液中有较好的析氢性能。稳定性测试表明,AuPdPt-WC/C纳米复合材料催化剂在模拟海水溶液中具有良好的稳定性。

To study the hydrogen evolution reaction(HER)from seawater electrolysis,nano-tungsten carbide promoted composite catalyst AuPdPt-WC/C was prepared by the direct chemical reduction methods.The hydrogen evolution property of the AuPdPt-WC/C electrode in simulated seawater was tested for the first time and proved with well catalytic activity.Cathodic polarization curves indicated that the AuPdPt-WC/C catalyst was of more positive hydrogen evolution over-potential and greater ability of depolarization than that of the commercial Pt/C catalyst.AuPdPt-WC/C catalyst expressed better performance for hydrogen evolution reaction in simulated seawater solution.The stability test showed that AuPdPt-WC/C nanocomposite catalyst in simulated seawater solution had a well stability.
