摘　　要：　利用热分解法制备了不同La含量的钛基Ru La Ti涂层阳极,并研究了所制备涂层的电催化性能。结果表明,在Ru Ti涂层阳极中掺杂稀土元素La可以提高涂层阳极的电催化活性,且La的掺杂量存在一个最佳范围(La的摩尔分数0.2)。涂层阳极电催化活性提高的原因在于La的引入可以提高涂层的有效活性表面积。Titanium based Ru\|La\|Ti coating anodes with various La compositions were prepared by thermal\|decomposition and the electrocatalytic activity of coating anodes were investigated. Results showed that the electrocatalytic ability of coating anodes could be improved by doping with rare earth La. The highest activity of coating anodes was associated with the composition corresponding to 0.2 (at mole fraction) La. The increase of electrocatalytic activity was attributed to the increase of its active surface area.
