Progress in metal-organic frameworks for small molecule oxidative coupled hydrogen production

The electrochemical oxidation reactions of small molecules present a lower theoretical thermodynamic potential in comparison to the oxygen evolution reaction (OER) and can serve as a viable alternative, concurrently generating value-added compounds or facilitating pollutant degradation. Metal-organic frameworks (MOFs) have garnered significant attention due to their adjustable properties, abundant active sites, and wide porosity in recent years. In comparison with conventional electrocatalysts, MOF-based electrocatalysts exhibit superior performance in the field of small molecule oxidation. A comprehensive review of synthesis methods and strategies for enhancing the electrochemical properties of MOF-based electrocatalysts has been provided, focusing on their applications in small molecule oxidation coupled with the hydrogen evolution reaction (HER). Furthermore, we address the current challenges and prospects to promote the development of more efficient MOF-based electrocatalysts for water splitting assisted by small molecule oxidation.
