This project aims to utilize visible light to control reactant adsorption on catalyst surfaces for accelerating reactions and tuning product selectivity. Visible light irradiation of plasmonic metal nanoparticles can generate a force that attracts reactant to the nanoparticles in a catalyst, and causes desorption of other reactant-types from the particles. These compound-selective effects can alter the concentrations of reactants at the catalyst surface, a new paradigm for optimising catalytic performance. This project expects to open new capabilities within fields of catalysis and light-matter interaction. The anticipated outcomes include significant advancement of knowledge in catalysis and new approaches for important chemical synthesis.

本计画旨在利用可见光来控制反应物在触媒表面的吸附，以加速反应及调整产物的选择性。等离子体金属纳米颗粒的可见光照射可以产生将反应物吸引到催化剂中的纳米颗粒的力，并导致其他反应物类型从颗粒解吸。这些化合物选择性效应可以改变催化剂表面的反应物浓度，这是优化催化性能的新范例。该项目预计将在催化和光物质相互作用领域开辟新的能力。预期成果包括催化知识的重大进步和重要化学合成的新方法。
