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.

形成具有精确定位的单个原子的活性位点是催化的最终目标。该项目旨在化学合成位于金属纳米颗粒载体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载体金属能够协同作用以增强催化。最新的理论模型，原位电子显微镜和同步加速器光谱技术将了解单原子网站。这些材料将用于析氢电催化，其中具有两种金属的活性位点极大地影响活性的反应。预期成果包括高性能水分解电解槽，以产生氢燃料。
