贵金属超小纳米颗粒(USNPs)具有高比表面积和高反应活性，在各种领域具有巨大的应用潜力。本工作利用由一株细小希瓦氏杆菌PV-4组成的电化学活性生物膜(EABs)，成功地合成了贵金属Au、Pd和Pt的USNPs。合成的USNPs的尺寸在2~7 nm之间，对染料的分解表现出良好的催化性能。这项工作的结果为EABs在纳米颗粒合成中的应用提供了参考。(C)2018年沙特国王大学。
Ultra-small nanoparticles (USNPs) of noble metals have a great potential in a variety of applications due to their high surface areas and high reactivity. This work employed electrochemically active biofilms (EABs) composed of a single bacterium strain of Shewanella loihica PV-4 and successfully synthesized USNPs of noble metal Au, Pd, and Pt. The synthesized USNPs had a size range between 2 and 7 nm and exhibited excellent catalytic performance in dye decomposition. The results of this work shine light on the use of EABs in nanoparticle synthesis. (C) 2018 King Saud University.
