Among renewable energy technologies, particular attention is paid to electrochemically transforming methanol into valuable formate and storing energy into supercapacitors. In this study, we detailed a simple colloidal‐based protocol for synthesizing a series of alloy nanoparticles with tuned Ni/Co atomic ratios, thereby optimizing their electrochemical performance. With the addition of 1 M methanol in 1 M KOH, the optimized composition was able to electrochemically produce formate at 0.149 mmol cm‐2 h‐1 with a Faradaic efficiency up to 95.1% at 0.6 V versus Hg/HgO within a 22‐hour testing period. In 1 M KOH solution without methanol, the supercapacitive performance was achieved at a specific capacitance of over 1500 F g‐1, and outstanding cycling stability with only approximately 20% decay after continuous 10000 charging‐discharging cycles. These results underscore that the prepared Ni‐Co alloy nanoparticles serve as multi‐functional electrodes for electrochemical energy conversion and storage, particularly in the MOR and supercapacitors applications.

In the quest to replace fossil fuels and reduce carbon dioxide emissions, developing energy technologies based on clean catalytic processes is fundamental. However, the costeffectiveness of these technologies strongly relies on the availability of efficient catalysts made of abundant elements. Herein, this study presents a one-step hydrothermal method to obtain a series of Ni 3 Se 4 nanoparticles with a layer of amorphous selenium on their surface. When employed as electrocatalysts for the methanol oxidation reaction (MOR), the optimized proper surface Se-coated Ni 3 Se 4 nanoparticles exhibit a high current density of 160 mA cm −2 at 1.6 V, achieving a high methanol-to-formate Faradaic efficiency above 97.8% and excellent stability with less than 20% current decay after an 18 h chronoamperometry test. This excellent performance is rationalized using density functional theory calculations, which unveil that the electrochemical recombination of SeO x results in a reduction of the energy barrier for the dehydrogenation of methanol during the MOR process.
