Metal-on-Metal Single Atom Catalysts

点击翻译按钮获取中文摘要

Forming active sites with precise positioning of individual atoms is an ultimate goal in catalysis. This project aims to chemically synthesise single metal atoms positioned on metal nanoparticle supports with precise atomic configurations. This enables the single metal atom and support metal to act synergistically for enhanced catalysis. The single atom sites will be understood by the very latest theoretical modelling, in situ electron microscopy and synchrotron spectroscopy techniques. These materials will be used for hydrogen evolution electrocatalysis, a reaction where having an active site with two metals greatly influences activity. The intended outcomes include high performance water splitting electrolysers to generate hydrogen fuel.
