This project aims to design and synthesize core-shell structured mesoporous semiconductors to improve the solar light absorption and quantum efficiency, as well as facilitate the interfacial photo-(electro-)catalytic reactions. The functions (such as visible-near infrared light absorption, photocatalytic reaction active centers, etc) and surface properties (such as crystal surface, defects, etc.) of the core-shell structured mesoporous composites will be precisely controlled to further improve the solar energy conversion efficiency of the resultant materials. At the same time, combined with omni-directional spectroscopy, structure characterizing techniques and theoretical calculation, the reactive centers and dynamic catalytic processing of the core-shell structured mesoporous photocatalysts will be analyzed to elucidate the synergistic effect of each component in the combined unit, the separation and migration pathway of the photogenerated electrons and holes as well as the adsorption and activation mechanism of interfacial molecules. Finally, the structure, interface, and properties related catalytic mechanism will be concluded, providing important thoughts and reliable experimental basis to produce highly efficient photocatalyst for the future study. Undoubtedly, this research will further enrich the types of functional mesoporous materials, improve the design and synthesis theory of nanomaterials, and expand the application of core-shell mesoporous materials in the fields of photocatalysis, electrocatalysis and photoelectric catalysis.
