Abstract
本发明涉及一种可控的双金属合金纳米颗粒的制备方法,所述双金属合金纳米颗粒为Pt/Pd-M合金纳米颗粒,其中M为Ni,Fe,Co,Mn,Pd,Zn,Cu,Mo中的一种,制备时,以正丁基锂作为强还原剂,以油胺、三正辛基膦作为保护剂,同时还原Pt/Pd-M(M=Ni,Fe,Co,Mn,Pd,Zn,Cu,Mo)的乙酰丙酮盐,氯化盐或乙酸盐,形成均一的、无浓度梯度的、尺寸可控的Pt/Pd-M合金纳米颗粒。本发明的制备工艺简单可控,解决了当两种金属前体还原电位差异太大时,一种金属被优先还原,难以获得合金纳米颗粒这一问题,为制备双金属合金纳米颗粒提供了一种更优的、通用的合成方法;为制备新一代的用于选择性加氢反应的金属-氧化物纳米杂化体催化剂提供关键前体
