Solution chemistry methods have been used to synthesize bimetallic CuPt alloy nanoparticle catalysts with controllable sizes and shapes. By variation of the relative ratios of the oleylamine and oleic acid stabilizers, solvent, and reduction rate, the nanoparticles could be tuned from approximately 2 nm spherical particles to nanorods with diameters of approximately 2.5 nm and aspect ratios tunable from 5:1 to 25:1. These mixed-metal nanoparticles show excellent catalytic properties for CO oxidation, with light-off temperatures that are nearly 200 K below those of conventional supported Pt catalysts.

长度可调的 CuPt 纳米棒催化剂的合成
溶液化学方法已被用于合成尺寸和形状可控的双金属 CuPt 合金纳米粒子催化剂。通过改变油胺和油酸稳定剂、溶剂和还原率的相对比例，纳米颗粒可以从大约 2 nm 的球形颗粒调整到直径约为 2.5 nm 且纵横比可从 5:1 调整到 25 的纳米棒： 1. 这些混合金属纳米粒子对 CO 氧化显示出优异的催化性能，起燃温度比传统负载型 Pt 催化剂低近 200 K。
