摘要
首先利用植酸钠作为稳定剂合成CuO纳米棒~([1])。第二步利用此CuO纳米棒通过还原法制备了Cu_2O修饰的Pd纳米网状结构。XPS分析结果显示,Cu_2O的引入对于Pd的电子结构进行了修饰。电化学测试表明,在甲醇氧化反应中,该催化剂表现出比商用催化剂显著提高的催化活性,抗毒化能力以及稳定性。这是由于独特的网状结构提供了更大的活性表面积,有利于反应快速进行,同时Pd与Cu_2O之间的协同作用不仅提高了Pd的利用率,而且Cu_2O上的含氧基团可以有效地氧化除去一氧化碳等含碳中间产物,使催化剂的抗毒化能力增加,稳定性增强~([2])。
The CuO nanorods(NRs) are prepared with the help of inositol hexakisphosphate which serves as a binding agent and stabilizer.Then Cu_2O-decorated palladium networks were successfully fabricated by using such CuO NRs as reaction beds.XPS analysis shows that the presence of Cu_2O modifies the electronic structure of Pd.Electrochemical results depict that the as-synthesized catalyst exhibits higher activity and CO-tolerance for methanol oxidation than the commercially available catalysts.The superior performance of the catalyst is attributed to the special network nanostructure as well as the synergistic effect between Pd and Cu_2O.
