中文摘要：

在柠檬酸钠溶液中,采用光化学Au晶种生长法合成Au核@Pt壳纳米粒子.应用UV-Vis、TEM和XPS等分析手段研究了Au@Pt纳米粒子的结构、形貌、化学状态等.研究结果表明,所合成的Au@Pt纳米粒子具有核-壳复合结构,平均粒径为7.3～10.2 nm

英文摘要：

Au core@Pt shell nano-particles were synthesized in sodium citrate solution by UV photochemical reduction and Au seeding growth.The structure,morphology and chemical state of the Au@Pt nano-particles were characterized using XPS,UV-Vis,and TEM.It was shown that the Au@Pt nano-particles had a core-shell composite structure with a mean size ranging from 7.3～10.2 nm.
