In the context of escalating energy demands and the imperative for sustainable energy solutions, this review delves into the promising realm of metal-organic frameworks (MOFs)-based supercapacitors (SCs) and their enhancement. SCs are heralded for their high power density, long cycle life, and environmental friendliness compared to traditional batteries. MOFs, with their high surface area, tunable pore structures and diverse chemical compositions, emerge as exceptional candidates for SC electrodes. This review explores the synthesis, structural modifications, and electrochemical performance of both monometallic and bimetallic MOFs, emphasizing their unique structural advantages and electroactive sites. The synergistic effects of incorporating different metal ions into MOFs significantly enhance their conductivity, stability, and overall electrochemical performance. The discussion extends to the challenges and future opportunities in this field, suggesting a focus on developing advanced synthesis techniques, optimizing metal ion doping, and integrating MOFs with conductive materials to create flexible and scalable energy storage solutions.
