Replacing the kinetically sluggish and energy-intensive oxygen evolution reaction (OER) at anode with oxidation of more thermodynamically favorable small organic molecules is a promising strategy for boosting hydrogen production. This study focuses on sustainable generation cathode facilitated by ethylene glycol (EGOR) anode, coupled production value-added formate. For this, we designed deposited cobalt- iron-based fluorinated two-dimensional (2D)-nanosheets (2D-CoFe@OF) through straightforward hydrothermal method onto nickel foam substrate (NF). The resulting 2D-CoFe@OF/NF exhibits an anodic potential that 100 mV lower in 0.5 M EG-added 1.0 KOH electrolyte to achieve benchmark electrolysis current density 10 mA cm–2, compared pure electrolyte. Additionally, assembling two identical 2D-CoFe@OF/NF||2D-CoFe@OF/NF electrode-based electrolyzers resulted 150 reduction operating cell voltage when electrolyzing particularly OER was replaced EGOR, thereby demonstrating significant improvement energy efficiency. Under this condition, electrolyzer demonstrated nearly 100% Faradaic efficiency (HER). Furthermore, practical application system studied EG-seawater suggests its replace freshwater abundant seawater, expanding horizon generation. study, thus, highlights 2D-CoFe@OF nanosheets EGOR advancing green technology toward future.
