摘要

本文首次报道了在没有任何封端剂和还原剂的情况下，利用超微气泡和超声合成 Au@Pd 核壳纳米粒子的过程。双金属核壳纳米粒子的平均直径受合成过程中超微气泡浓度的控制。钯壳的厚度也随着钯（II）离子浓度的变化而变化。这些 Au@Pd 核壳纳米粒子表面纯净，不含任何封端剂和还原剂，因此表现出优异的催化性能。

Synthesis of Au@Pd core-shell nanoparticles by ultrafine bubbles and ultrasound without capping and reducing agents

This paper, for the first time, reports on synthesis of Au@Pd core-shell nanoparticles in the absence of any capping and reducing agents by ultrafine bubbles and ultrasound. The mean diameter of the bimetallic core-shell nanoparticles was controlled by the ultrafine bubble concentration during the synthesis. The Pd shell thickness also varied with the concentration of Pd(II) ions. These Au@Pd core-shell nanoparticles showed excellent catalytic performance due to the pure surface without any capping and reducing agents.
