Abstract:
Direct conversion of solar energy into chemical energy in an environmentally friendly manner is one of the most promising strategies to deal with the environmental pollution and energy crisis. Among a variety of materials developed as photocatalysts, the core-shell metal/covalent-organic framework (MOF or COF) photocatalysts have garnered significant attention due to their highly porous structure and the adjustability in both structure and functionality. The existing reviews on core-shell organic framework photocatalytic materials have mainly focused on core-shell MOF materials. However, there is still a lack of in-depth reviews specifically addressing the photocatalytic performance of core-shell COFs and MOFs@COFs. Simultaneously, there is an urgent need for a comprehensive review encompassing these three types of core-shell structures. Based on this, this review aims to provide a comprehensive understanding and useful guidelines for the exploration of suitable core-shell organic framework photocatalysts towards appropriate photocatalytic energy conversion and environmental governance. Firstly, the classification, synthesis, formation mechanisms, and reasonable regulation of core-shell organic framework were summarized. Then, the photocatalytic applications of these three kinds of core-shell structures in different areas, such as H2 evolution, CO2 reduction, and pollutants degradation are emphasized. Finally, the main challenges and development prospects of core-shell organic framework photocatalysts were introduced. This review aims to provide insights into the development of a novel generation of efficient and stable core-shell organic framework materials for energy conversion and environmental remediation.
