A general strategy for preparation of Pt 3d-transition metal (Co, Fe, Ni) nanocubes.

摘要: A facile, reliable, general, and robust synthetic method for preparation of high-quality, (100)-terminated Pt3M nanocubes (M = Pt or 3d-transition metals Co, Fe, Ni) has been developed. It was identified that addition W(CO)6 is crucial control the nucleation process when metallic precursors are reduced, whereas an optimized ratio solvent pair, oleylamine oleic acid, key to enabling lowest total surface energy on {100} facets in order develop cubic nanocrystals present system. The resultant monodisperse nanocubes, which partially substituted, expected exhibit unusual electrocatalytic characteristics, providing alternative developing high-performance electrocatalysts use fuel cells.
