Metal-on-Metal Single Atom Catalysts

精确定位单个原子形成活性位点是催化的最终目标。该项目旨在化学合成定位在金属纳米颗粒支架上的具有精确原子构型的单个金属原子。这使得单个金属原子和支撑金属协同作用以增强催化作用。单原子位置将通过最新的理论模型、原位电子显微镜和同步加速器光谱技术来理解。这些材料将用于析氢电催化，这是一种具有两种金属的活性位点对活性有很大影响的反应。预期的结果包括高性能的水分解电解槽，以产生氢燃料。

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.
