There is a great deal of interest in the development electrocatalysts for oxygen evolution reaction (OER) that are stable and have high activity because this anodic half-reaction main bottleneck water splitting other key technologies. Cobalt iron oxide oxyhydroxide constitute cheaper alternative to highly active commonly used Ir- Ru-based catalysts. Most described require tedious synthetic expensive preparation procedures. We report here facile straightforward an electrocatalyst by combination commercial compounds, such as cobalt chloride ferrocene. A OER obtained, which shows low overpotential alkaline medium consequence synergistic effect between both compounds inexpensive.

The upsurging of cost-effective de novo electrocatalysts through the operando electro-oxidation approaches holds great promise for scalable production green energy in pursuit sustainability. This work introduces an reconstitution strategy producing a smart electrocatalyst, cobalt "oxyhydroxide" derived from newly designed 2D cobalt(II) metal–organic framework (NBU-4) directly grown on nickel foam (NF), NBU-4/NF@CoOOH. NBU-4/NF@CoOOH, exhibits outstanding overpotential 76 mV hydrogen evolution reaction and 336 oxygen to achieve current density 10 mA/cm2 with remarkable Faradaic efficiencies 97.1 93.4%, respectively, 1 M aqueous KOH.

The pursuit of sustainable energy solutions to address environmental challenges and crises has driven significant interest in electrocatalytic water splitting. However, the efficiency this process is hindered by sluggish kinetics anodic oxygen evolution reaction (OER). To overcome this, we synthesized two isoreticular cobalt-based metal-organic frameworks (MOFs), MOF-74 MOF-274, with different pore sizes (16.50 23.37 Å, respectively), where exhibited stronger Fe(III) adsorption as a result its confined nanosized channels. Electrochemical activation transformed these Co-MOF precatalysts into Fe-doped CoOOH nanosheets uniform elemental distribution, enhancing their OER performance. It revealed strengthened Co-O-Fe electronic interactions MOF-74-Fe X-ray photoelectron spectroscopy analysis, MOF-74-Fe-OER achieved decent activity show lower overpotential 288 mV at 10 mA cm-2 compared MOF-274-Fe-OER (357 mV). Furthermore, long-term stability tests confirmed robust durability, retaining 96.9% initial performance over h. These results underscore critical role pore-engineered MOF optimizing modulation catalytic for oxidation.
