We report a facile, seed-mediated method to synthesize nanoscale gold truncated ditetragonal nanoprisms (TDPs) enclosed by 12 high-index {310} facets. The method leads to the formation of nanoparticles with high size and shape monodispersity and allows for easy surfactant removal. The dependence of particle shape on the synergetic contribution of metallic ions, halide ions, and surfactant adsorbates during synthesis is described. The resulting high-index nanoparticle facets were demonstrated as efficient activators of a supported catalytic material (platinum). A Pt monolayer deposited onto the Au TDP nanofacets with sharp electrochemical signatures exhibits an enhanced catalytic activity.

截断双四方金棱柱作为催化铂的纳米面活化剂

我们报告了一种简便的、种子介导的方法来合成由 12 个高指数 {310} 面包围的纳米级金截断双四方纳米棱柱 (TDP)。该方法导致形成具有高尺寸和形状单分散性的纳米颗粒，并允许轻松去除表面活性剂。描述了合成过程中颗粒形状对金属离子、卤化物离子和表面活性剂吸附物的协同贡献的依赖性。由此产生的高指数纳米颗粒面被证明是负载催化材料（铂）的有效活化剂。沉积在具有尖锐电化学特征的 Au TDP 纳米面上的 Pt 单层表现出增强的催化活性。
