Article Improved Methanol-to-Formate Electrocatalytic Reaction by Engineering of Nickel Hydroxide and Iron Oxyhydroxide Heterostructures Ning Jian 1,2, Huan Ge Yi Ma Yong Zhang Luming Li Junfeng Liu 3, Jing Yu 4, Canhuang Junshan 1,2,* 1 School Mechanic Engineering, Chengdu University, 610106, China 2 Institute for Advanced Study, 3 Energy Research, Jiangsu 212013, 4 Catalonia Research-IREC, Sant Adrià de Besòs, Barcelona 08930, Spain * Correspondence: [email protected] Received: 8 March 2025; Revised: 21 Accepted: 25 Published: 27 2025 Abstract: methanol oxidation reaction (MOR) holds significant value in the chemical industry, as it enables treatment methanol-containing wastewater promotes hydrogen production from water. 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.
