Metal and covalent organic frameworks (MOFs/COFs) are emerging promising candidates in the field of catalysts due to their porous nature, chemically well-defined active sites and structural diversity. However, they are typically provided with poor electrical conductivity, which is insufficient for them to work as satisfying electrocatalysts. Designing and fabricating MOFs/COFs with high conductivity presents a new avenue towards special electrochemical reactions. This minireview firstly highlighted the origin and design principles of conductive MOFs/COFs for electrocatalysis on the basis of typical charge transfer mechanisms, that is "through space", "extended conjugation" and "through bond". An overview of conductive MOFs/COFs used in the electrocatalytic carbon dioxide reduction reaction (CORR), water splitting and the oxygen reduction reaction (ORR) was then made to track the very recent progress. In the final remarks, the present challenges and perspectives for the use of conductive MOFs/COFs as electrocatalysts including their structural optimization, feasible applications and structure-activity correlation are proposed.
金属和共价有机框架材料（MOFs/COFs）因其多孔性质、化学性质明确的活性位点和结构多样性，在催化剂领域正成为有前景的候选材料。然而，它们通常导电性较差，不足以作为令人满意的电催化剂发挥作用。设计和制造具有高导电性的MOFs/COFs为特殊电化学反应开辟了一条新途径。本综述首先基于典型的电荷转移机制，即“空间传导”、“扩展共轭”和“键传导”，突出了用于电催化的导电MOFs/COFs的起源和设计原则。然后概述了导电MOFs/COFs在电催化二氧化碳还原反应（CORR）、水分解和氧还原反应（ORR）中的应用，以追踪最新进展。在结语中，提出了将导电MOFs/COFs用作电催化剂目前面临的挑战和前景，包括它们的结构优化、可行应用以及结构-活性相关性。
