采用一种简单的电化学方法，在刘易斯酸性ZnCl 2 -1-乙基-3-甲基咪唑氯化物离子液体中，通过PtZn的合金化和去合金化制备了高比表面积纳米结构铂电极。由于表面积增加，所得Pt电极显示出显著增强的氢和甲醇氧化还原反应电流。
A simple electrochemical strategy is described to prepare high surface area nanostructured platinum electrode by alloying and de-alloying of PtZn in a Lewis acidic ZnCl2-1-ethyl-3-methylimidazolium chloride ionic liquid. The resulting Pt electrode showed significantly enhanced current for hydrogen and methanol redox reactions, due to the increased surface area.
