Development of Mn-MOF/CuO composites as platform for efficient electrocatalytic OER

Environmental contamination and an energy shortage pose severe threats to the long-term viability of the modern civilization. The production of sustainable, long-lasting storing energy and a clean means to create hydrogen are both made possible through electrolysis of water. Metal-organic frameworks and their composites have nowadays become the most efficient multipurpose nanomaterials due to their large contact area, changeable permeability, adaptability of framework, and capacity to be employed as constituents with such a variety of structural shapes. For the OER process in 1 M potassium hydroxide electrolyte, the n-MOF/CuO nanoparticles were fabricated using a hydrothermal technique in the current study. The produced electrode materials were characterised by examining their form, crystalline nature, and oxidation states using a wide range of analytical approaches. Overall, the composite exhibits a low overpotential of 247 mV to obtain a power density of 10 mA/cm⁻², a smaller Tafel slope of 48 mV dec^-1, and also provides durability for 50-hours period. This research provides a straightforward synthesized approach for making incredibly beneficial, inexpensive, and binder-free electrode materials.
