研究了Au和Au-Pd核壳纳米粒子在液-液界面上的催化活性。所示的颗粒催化的过程，这是由于界面氧还原。的Au-Pd颗粒被证明是更积极的和催化活性和颗粒半径，表面积和浓度之间的相关性给洞察的催化过程的机制。还与通过使用金线在液体半电池之间进行接触而形成的类似双极配置进行比较。(C)2013作者由爱思唯尔有限公司出版。保留所有权利。
The catalytic activity of Au and Au-Pd core-shell nanoparticles is investigated at the liquid-liquid interface. The particles are shown to catalyse a process which is attributed to interfacial oxygen reduction. The Au-Pd particles are shown to be more active and correlations made between the catalytic activity and particle radius, surface area and concentration give insight into the mechanism of the catalytic process. Comparison is also made with an analogous bipolar configuration, formed by making contact between the liquid half-cells using a gold wire. (C) 2013 The Authors. Published by Elsevier Ltd.
