This project aims to develop photocatalysis of supported metal nanoparticles to drive various chemical synthesis reactions at moderate temperatures using sunlight. The nanostructures of plasmonic metals (gold, silver and copper) are used as light absorbers to concentrate the energy of incident light and generate intense electromagnetic field, which are utilised to promote the catalytic reactions on transition metals in the photocatalysts. The mechanisms of these new photocatalytic processes will be defined. Successful completion of this project will result in new strategies for catalytic chemical synthesis and valuable knowledge within the areas of catalysis, conversion of solar energy to chemical energy, and nanomaterials.

该项目旨在开发负载型金属纳米颗粒的光催化，以利用太阳光在中等温度下驱动各种化学合成反应。利用等离子体金属(金、银和铜)的纳米结构作为光吸收体，集中入射光的能量，产生强烈的电磁场，从而促进光催化剂中过渡金属的催化反应。这些新的光催化过程的机理将被定义。该项目的成功完成将带来催化化学合成的新战略和在催化、将太阳能转换为化学能和纳米材料领域的宝贵知识。
