Structural Design of <scp>MOF</scp> ‐Based and <scp>MOF</scp> ‐Derived Composites for Oxygen Evolution Electrocatalysis: Materials Innovation for Energy and Environmental Sustainability

To achieve sustainable renewable energy, there is an urgent need for efficient electrocatalyst. Such electrocatalyst must have capability to drive the water electrolysis with significant stability and electrocatalytic activity. The metal organic framework and their derivatives have become popular material due to its porosity and tunable coordination framework. However, their restricted conductivity and structural delicateness limit their full exploration. Therefore, to reduce their inherent limitation, recently MOF‐based and MOF‐derived composites (MOF‐GO, MOF‐Polymer, and MOF‐MXene) with versatile architecture have been developed. Therefore, such MOF composite can offer improved charge transfer kinetics, high exposure of active sites during electrochemical studies. In this context, this comprehensive review offers a critical assessment of the recent advancement of MOF and MOF‐based and MOF‐derived composites for the oxygen evolution reaction. This review will highlight how structural design and interfacial engineering can dictate electrocatalytic performance. Additionally, to illustrate the contribution of redox‐active metal centers, organic ligands, and hierarchical porosity, significant example and cases are thoroughly discussed. Finally, opportunities and challenges are outlined, including scalable synthesis, in situ/operando insights, and incorporation into practical electrolyzer systems.
