In this work, by utilizing galvanic replacement reaction, a simple method for the synthesis of trimetallic PtCuCo hollow nanospheres with a dendritic shell is demonstrated. The compositions of the nanospheres can be well controlled, and the electrocatalytic activity can also be modulated by adjusting their compositions. Electrocatalytic results show that all of the as-prepared trimetallic PtCuCo nanomaterials show better catalytic performance toward ethylene glycol electrooxidation than the commercial catalyst.
在这项工作中，通过利用电化置换反应，展示了一种合成具有树枝状壳层的三金属PtCuCo空心纳米球的简单方法。纳米球的组成可以得到很好的控制，并且通过调整其组成也可以调节电催化活性。电催化结果表明，所有制备的三金属PtCuCo纳米材料对乙二醇电氧化的催化性能均优于商业催化剂。
