In the quest to replace fossil fuels and reduce carbon dioxide emissions, developing energy technologies based on clean catalytic processes is fundamental. However, cost-effectiveness of these strongly relies availability efficient catalysts made abundant elements. Herein, this study presents a one-step hydrothermal method obtain series Ni3Se4 nanoparticles with layer amorphous selenium their surface. When employed as electrocatalysts for methanol oxidation reaction (MOR), optimized proper surface Se-coated exhibit high current density 160 mA cm–2 at 1.6 V, achieving methanol-to-formate Faradaic efficiency above 97.8% excellent stability less than 20% decay after an 18 h chronoamperometry test. This performance rationalized using functional theory calculations, which unveil that electrochemical recombination SeOx results in reduction barrier dehydrogenation during MOR process.

This study investigates a strategy based on tuning-composition metal elements to optimize MOR performance, aiming outperform current cost-effective efficient catalysts. To this end, nickel hydroxide iron oxyhydroxide heterostructures were synthesized through facile hydrothermal routine, catalytic performance three different Ni/Fe ratios was examined alkaline media. Among them, material with equal ratio exhibited best activity, maintaining high density ~66 mA cm−2 at 1.5 V vs. RHE M KOH electrolyte methanol. Moreover, developed electrode showed Faradaic efficiency (FE) 98.5% formate within continuous 12 h test. Furthermore, function theory (DFT) calculation applied unravel methanol-to-formate conversion mechanism that enhanced proper ratio. These results demonstrate selectivity NiFe-based materials, providing promising non-precious catalyst electrocatalytic upgrading value-added formate.
