Fabrication of metal nano-particles (NPs) and metal alloy NPs with controlled size, morphology and composition is an essential technology for the design of active metal catalysts. In this project, we prepared "Single-site photocatalysts" as platform materials by embedding various transition metal species into the framework of nanoporous materials. By utilizing the reduction ability of "Single-site photocatalysts" which is induced by ultraviolet light or microwave irradiations, various types of metal NPs and metal alloy NPs with controlled size, morphology and composition were successfully synthesized. The thus synthesized metal NPs exhibited high catalytic activities in particular selective reactions. In addition, by utilizing the surface plasmon resonance property of metal NPs, unique luminescent nanomaterials and photocatalysts were also developed.

制备尺寸、形貌和成分可控的金属纳米粒子和金属合金纳米粒子是设计活性金属催化剂的关键技术。在本项目中，我们通过将各种过渡金属物种嵌入到纳米多孔材料的骨架中，制备了作为平台材料的单位光催化剂。利用紫外光或微波辐射诱导的单位光催化剂的还原能力，成功地合成了尺寸、形貌和成分可控的各种类型的金属纳米粒子和金属合金纳米粒子。这样合成的金属纳米粒子具有很高的催化活性，特别是选择性反应。此外，利用金属纳米粒子的表面等离子体共振特性，还开发了独特的发光纳米材料和光催化剂。
