Abstract Transition metal complexes are well‐known homogeneous electrocatalysts. In this regard, metal–organic frameworks (MOFs) can be considered as an ensemble of transition ordered in a periodic arrangement. addition, MOFs have several additional positive structural features that make them suitable for electrocatalysis, including large surface area, high porosity, and content accessible with exchangeable coordination positions. The present review describes the current state use electrocatalysts, both host electroactive guests their direct electrocatalytic activity, particularly case bimetallic MOFs. field MOF‐derived materials is purposely not covered, focusing on or its composites Special attention has been paid to strategies overcome poor electrical conductivity limited stability.
