Design of Nano Metal Catalysts Using Single-site Photocatalysts

制备具有可控尺寸、形貌和组成的金属纳米颗粒（NPs）和金属合金NPs是设计活性金属催化剂的必要技术。在本项目中，我们通过将各种过渡金属物种嵌入纳米多孔材料的框架中来制备作为平台材料的“单活性中心光催化剂”。利用“单活性中心光催化剂”在紫外光或微波辐照下的还原能力，成功地合成了尺寸、形貌和组成可控的各种类型的金属纳米颗粒和金属合金纳米颗粒。由此合成的金属NP在特别的选择性反应中表现出高催化活性。此外，利用金属纳米颗粒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。

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.
