摘要/Abstract

共价有机框架（Covalent Organic Frameworks，COFs）是一类由有机结构单元通过共价键连接形成的多孔框架晶体材料，具有密度低、比表面积大和热稳定性高等特点，在分子吸附与分离、传感、催化、光电器件等领域存在着广阔的应用前景.近年来，基于其固有结构特点，二维COFs在能源领域中的应用潜力也逐渐引起了科学界的关注.本文主要综述了二维COFs材料在能源存储（锂离子电池、锂硫电池、超级电容器、燃料电池）和能源转化（水分解反应以及CO₂还原反应）等方面的研究进展，并对其研究前景进行了展望.

Covalent organic frameworks (COFs) are a class of porous crystalline materials consisting of organic units connected through covalent bonds. Due to their low density, high surface area and high thermal stability, COFs have found interesting applications in many fields, including molecular adsorption and separation, sensing, catalysis and optoelectronics devices. In particular, two-dimensional (2D) COFs have attracted increasing attention in energy fields. In this perspective, the applications of 2D COFs in energy storage (lithium ion batteries, lithium-sulfur batteries, supercapacitor and fuel cells) and energy conversion (water splitting and reduction of carbon dioxide) are reviewed. In addition, we will also discuss the remaining challenging issues.
Key words: covalent organic frameworks, rechargeable batteries, supercapacitor, fuel cells, water splitting, CO₂ reduction
