我们报道了嵌段共聚物辅助合成了包覆有纳米树枝状铂外壳的金金属核(Au@Pt)。本文采用Pluronic F127嵌段共聚物催化抗坏血酸(AA)还原铂和Au络合物，提出了一种快速、一步、高效的湿化学法高产率(接近100%)直接合成Au@Pt.
We report block copolymer assisted synthesis of a Au metal core coated with a nanodendritic Pt shell (Au@Pt). Herein, a rapid, one-step and efficient wet-chemical route is proposed to straightforwardly synthesize Au@Pt with high yield (similar to 100%), which was mediated by Pluronic F127 block copolymer from the reduction of Pt and Au complexes by ascorbic acid (AA).
