Modular design in metal-organic frameworks for oxygen evolution reaction

Among the cutting-edge materials for catalysis, metal-organic frameworks (MOFs) have become popular. The application has gradually shifted from organic synthesis to electro-catalysis in recent years. MOFs based on various transitions metals have exhibited excel-lent performance for electrocatalysis. The oxygen evolution reaction (OER) is an essential process for electrocatalysis, developing efficient OER electrocatalysts is challenging. Herein, a new model design is presented based on MOFs. By establishing the proper link between these modules, researchers may correctly and effectively synthesize hollow nanostructured MOFs, electrically conducting MOFs, hierarchically porous MOFs, func-tionalized MOFs and two-dimensional MOFs. The difficulties and potential of MOF-based catalysts for OER research are finally highlighted. Ultimately, the modular design concept examined in this study might be a useful tool for examining the relationships between structure and activity and accelerating the design of multi-component electro-catalysts on supply.
