Clean energy conversion and storage require simple, economical, effective electrode materials to achieve promising results. The development of high-performance electrocatalysts with adequate stability cost-effectiveness is essential ensure low overpotentials toward the oxygen evolution reaction (OER). Herein, a cobalt-based metal-organic framework 4,4,4-6T14 topology in combination various ratios NiMn-layered double hydroxide (Co-MOF@X%NiMn-LDH, X = 5, 10, 20, 40%) applied as an electrocatalyst for oxidation water. optimum sample, Co-MOF@20%NiMn-LDH nanocomposite, showed overpotential 174 mV at current density 10 mA cm-2 reduced Tafel slope 64 dec-1 1 M KOH, which makes it excellent candidate, significantly superior commercial IrO2 most MOF- LDH-based electrocatalysts. Chronopotentiometry tests OER over several hours confirmed that these have been sufficiently stable. Pillared MOFs can obstruct active entities from NiMn-LDH cubic agglomeration, thus facilitating mass transportation ensuring continuous exposure sites. Accordingly, synthesized composite demonstrates considerable electrocatalytic efficiency OER, consequence porous structure, external surface area, synergistic effects among Co-MOF samples.

Global clean energy demands can be effectively addressed using the promising approach of hydrogen generation combined with less consumption. Hydrogen generated, and urea-rich wastewater pollution mitigated in a low-energy manner urea oxidation reaction (UOR). This paper seeks to assemble unique electrocatalyst pristine 2D MOF, [Co(HBTC)(DMF)]n (Co-MUM-3), from 1,3,5-benzenetricarboxylate (BTC) oxidize simulated seawater. Ni foam (NF)-based working electrodes were fabricated by incorporating series heterometallic CuCo-MUM-3 frameworks (Cu0.1Co0.9-MUM-3, Cu0.2Co0.8-MUM-3, Cu0.3Co0.7-MUM-3, Cu0.4Co0.6-MUM-3), after which their application was examined.
