Abstract
The persistent increase in atmospheric carbon dioxide (CO2 ) concentration poses a significant contemporary challenge. Contemporary chemistry is heavily focused on sustainable solutions, particularly the photo-/electrocatalytic reduction of CO2 and its utilization for energy storage. Despite promising prospects, efficient chemical CO2 conversion faces obstacles such as ineffective CO2 uptake/activation and catalyst mass transport. Covalent organic frameworks (COFs) have emerged as potential catalysts due to their precise structural design, functionalizable chemical environments, and robust architectures. COF-based materials, especially those incorporating diverse active sites like single metal sites, metal nanoparticles, and metal oxides, hold promise for CO2 conversion and energy storage. This review sheds light on CO2 photoreduction/electroreduction and storage in Li-CO2 batteries catalyzed by COF-based composites, focusing on recent advancements in integrating COFs with nanoparticles for CO2 reduction. It discusses design principles, synthesis methods, and catalytic mechanisms driving the enhanced performance of COF-based nanocomposites across various applications, including electrochemical reduction, photocatalysis, and lithium CO2 batteries. The review also addresses challenges and prospects of COF-based catalysts for efficient CO2 utilization, aiming to steer the development of innovative COF-based nanocomposites, thus advancing sustainable energy technologies and environmental stewardship. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.
基于共价有机框架的纳米复合材料的进展:用于减少和储存二氧化碳的先锋材料
大气中二氧化碳(CO2)浓度的持续上升对当代提出了重大挑战。当代化学高度关注可持续的解决方案,特别是光催化/电催化还原二氧化碳并将其用于能源储存。尽管前景广阔,但高效的二氧化碳化学转化仍面临着二氧化碳吸收/活化效果不佳和催化剂质量迁移等障碍。共价有机框架(COF)因其精确的结构设计、可功能化的化学环境和坚固的结构而成为潜在的催化剂。以 COF 为基础的材料,尤其是那些包含多种活性位点(如单一金属位点、金属纳米颗粒和金属氧化物)的材料,有望用于二氧化碳转化和能量存储。本综述阐明了 COF 基复合材料催化的 CO2 光还原/电还原以及锂-CO2 电池中的 CO2 储能,重点介绍了将 COF 与纳米颗粒整合用于 CO2 还原的最新进展。报告讨论了设计原理、合成方法和催化机制,这些因素推动了基于 COF 的纳米复合材料在电化学还原、光催化和二氧化碳锂电池等各种应用中性能的提高。综述还探讨了基于 COF 的催化剂在高效利用二氧化碳方面所面临的挑战和前景,旨在引导基于 COF 的创新型纳米复合材料的发展,从而推动可持续能源技术和环境管理。© 2024 化学工业协会和 John Wiley & Sons, Ltd. 保留所有权利。
