A decade of breakthroughs: MOF-graphene oxide catalysts for water splitting efficiency

Abstract Burning fossil fuels has significantly worsened environmental pollution, particularly due to the release of carbon dioxide emissions. The global efforts to promote renewable energy solutions, like electrocatalytic water splitting, have gained momentum. Scientists are focusing on the development of sustainable methods like water splitting to reduce dependence on conventional fuels. Developing affordable and effective electrocatalysts is crucial for multifunctional electrochemical water splitting (ECWS). In comparison to traditional electrocatalysts, metal-organic frameworks (MOFs) exhibit favorable catalytic performance for electrochemical water decomposition because of their plentiful porosity, surface area, and topologies for enhanced production of hydrogen (H 2 ) and oxygen (O 2 ) gas. When combined with MOF, graphene creates a synergistic hybrid nanomaterial that is more stable, adaptable, and durable. The primary goal of this review article is to conduct an in-depth investigation of the latest advancements in MOFs and MOF-GO electrocatalysts for water electrolysis. Herein, we have covered the plausible mechanism for the overall water-splitting electrocatalytic processes and several important factors influencing their electrocatalytic response. We also discussed the recent progress in the performance and stability of MOFs and MOF-GO electrocatalysts for water-splitting reactions. Finally, the article highlights the challenges and application of MOF and MOF-GO composites and the future preference for water-splitting applications.
