Subsequently, these structures are employed as potent electrocatalysts for the anodic methanol oxidation reaction (MOR), offering an alternative to the sluggish oxygen evolution reaction (OER). Electrochemical assessments indicate that the Co\u2013CuO catalyst exhibits exceptional MOR activity, requiring a reduced potential of 1.42\u00a0V at 10 mA\u00a0cm<jats:sup>\u20132<\/jats:sup> compared to that of pure CuO catalyst (1.57\u00a0V at 10 mA\u00a0cm<jats:sup>\u20132<\/jats:sup>). Impressively, the Co\u2013CuO catalyst achieved a nearly 180\u00a0mV potential reduction in MOR compared to its OER performance (1.60\u00a0V at 10 mA cm<jats:sup>\u22122<\/jats:sup>). Furthermore, when pairing Co\u2013CuO(+)\u01c0\u01c0Pt\/C(\u2212) in methanol electrolysis, the cell voltage required is only 1.51\u00a0V at 10 mA\u00a0cm<jats:sup>\u22122<\/jats:sup>, maintaining remarkable stability over 12\u00a0h. This represents a substantial voltage reduction of \u2248160\u00a0mV relative to conventional water electrolysis (1.67\u00a0V at 10 mA\u00a0cm<jats:sup>\u22122<\/jats:sup>). Additionally, both in situ<jats:italic>\/operando<\/jats:italic> Raman spectroscopy studies and theoretical calculations have confirmed that Co\u2010doping plays a crucial role in enhancing the activity of the Co\u2013CuO catalyst. This research introduces a novel synthetic approach for fabricating high\u2010efficiency electrocatalysts for large\u2010scale hydrogen production while co\u2010synthesizing value\u2010added formic
