The perfect strategy for the generation of green and renewable hydrogen (H2) fuels is direct electrocatalytic splitting plentiful seawater rather than scarce freshwater. One half-reactions taking place during oxygen evolution (OER). However, OER affected by slow four-electron transfer kinetics as well competitive chlorine reactions (CERs) in seawater. To overcome kinematic barriers achieve an excellent overall performance splitting, we herein report a facile, low-cost, one-step fabrication procedure 3D structured nickel–manganese (NiMn) coatings using dynamic bubble template (DHBT) technique. activities thus synthesized catalytic materials simulated (0.5 M NaCl + 1 KOH, denoted SSW) alkaline natural (natural ASW) were investigated linear sweep voltammetry (LSV) at varying temperatures from 25 to 75 °C. Scanning electron microscopy (SEM) inductively coupled plasma–optical emission spectroscopy (ICP–OES) used examine surface morphology composition prepared catalysts. It was found that NiMn/Ti-1 catalyst plating bath containing molar ratio 1:1 Ni2+:Mn2+ having lowest Mn loading 13.43 µg cm−2 exhibited quite reasonable activity Cl− ion rich SSW ASW. benchmark current density 10 mA ASW, electrocatalyst requires overpotentials 386 388 mV, respectively. In addition, this optimal bimetallic also demonstrated superior long-run stability 1.81 V (vs. RHE) 24 h both working electrolytes. Impressively, two-electrode electrolyzer—NiMn/Ti-5(−)||NiMn/Ti-1(+)—needs only 1.619 deliver electrolysis, which even 0.075 lower noble metal-based electrolyzer (Pt(−)||NiMn/Ti-1(+)).
