摘要
以三氯化钌、二氯化锰和柠檬酸为源物质,正丁醇为溶剂,采用溶胶凝胶法制备了钌锰二元氧化物涂层钛阴极。通过XRD、SEM、电化学方法,研究了涂层的表面形貌,组织结构及其对涂层的析氢电催化活性的影响。结果表明,在涂层中,钌和锰组元分别以金红石相的RuO2和尖晶石相的Mn2O3的形式存在,Mn2O3能有效提高涂层的析氢电催化活性。
The binary Ru-Mn oxide-coated titanium electrodes were prepared by sol-gel method, using RuCl3, MnCl2 and citric acid as raw substance,n-butanol as solvent. The microstructures, morphologies and the cathode electroeatalysis activities of the coatings were studied by XRD,SEM,and electrochemistry test. It is demonstrated that in the coatings Ru and Mn components exist in the forms of rutile RuO2 and spinel Mn2O3 ,respectively. Adding spinel Mn2O3 can increase the electrocatalysis activity for hydrogen evolution.
