A facile, reliable, general, and robust synthetic method for preparation of high-quality, (100)-terminated Pt(3)M nanocubes (M = Pt or 3d-transition metals Co, Fe, and Ni) has been developed. It was identified that addition of W(CO)(6) is crucial for control of the nucleation process when the metallic precursors are reduced, whereas an optimized ratio of the solvent pair, oleylamine and oleic acid, is the key to enabling the lowest total surface energy on {100} facets in order to develop cubic nanocrystals in the present system. The resultant monodisperse nanocubes, in which Pt is partially substituted, are expected to exhibit unusual electrocatalytic characteristics, providing an alternative for developing high-performance electrocatalysts for use in fuel cells.

制备 Pt 3d-过渡金属（Co、Fe、Ni）纳米立方体的一般策略

已开发出一种简便、可靠、通用且稳健的合成方法，用于制备高质量的 (100) 封端 Pt(3)M 纳米立方体（M = Pt 或 3d 过渡金属 Co、Fe 和 Ni）。已经确定，当金属前体减少时，W(CO)(6) 的添加对于控制成核过程至关重要，而溶剂对、油胺和油酸的优化比例是实现最低总量的关键{100} 面上的表面能以在本系统中开发立方纳米晶体。由此产生的单分散纳米立方体，其中 Pt 被部分取代，有望表现出不寻常的电催化特性，为开发用于燃料电池的高性能电催化剂提供了替代方案。
