Tetrahexahedral, polyhedral, and branched Pd@Au core-shell nanostructures were selectively produced by manipulating their growth thermodynamics and kinetics. The current density in the electrochemical oxidation of H2O2 and the electrochemiluminescence density of luminol-H2O2 systems at the tetrahexahedron modified electrode are 43.5 and 16.4 times that at the bulk Au electrode, respectively.
通过控制生长热力学和动力学，选择性地制备出了四面体、多面体和支化的 Pd@Au 核壳纳米结构。在四面体修饰电极上，H2O2 的电化学氧化电流密度和鲁米诺-H2O2 体系的电化学发光密度分别是体相 Au 电极的 43.5 倍和 16.4 倍。
