摘要

该研究展示了一种通过化学还原通过改变金属成分和封盖剂类型来快速生产PtPd的方法。通过调整体积比为3:1、1:3和1:1的两种金属前驱体Pt和Pd，并将其与单一金属前驱体进行比较，研究了Pt和Pd两种金属前驱体组成的影响。FESEM结果表明，制备的样品均呈现纳米海绵结构。1:1配比的PtPd的ECSA值最高，为14.25 m2 /g，而添加PVP的PtPd的ECSA值为692.7 m2 /g，高于未添加封盖剂的PtPd的ECSA值(287.8 m2 /g)，表明其活性位点较大，增强了其催化功能。

Tuning the properties of PtPd nanoparticles by varying metal composition and capping agents

This study demonstrated a rapid method of producing PtPd via chemical reduction by varying metal composition and types of capping agents. The effect of different compositions between the two-metal precursor, Pt and Pd, is invested by tuning at various volume ratios of 3:1, 1:3, and 1:1 and comparing them with their single counterparts. The FESEM results show that all prepared samples exhibit nanosponges structure. PtPd of 1:1 ratio has the highest ECSA of 14.25 m2 /g, while PtPd with PVP exhibits a high ECSA value of 692.7 m2 /g compared to those without capping agent (287.8 m2 /g), indicating large active sites, which increases its catalytic function.
