Ni₂CoS₄ was prepared by the liquid-phase method and applied to the benzyl alcohol electro-oxidation reaction (BAOR), demonstrating excellent catalytic activity [with a current density of 271 mA·cm^-2 at 1.40 V (vs RHE)] and long-term stability. The S-anion effect can regulate the charge distribution on the catalyst surface, thereby enhancing the additional adsorption capacity of OH^- at the Co sites. By combining material characterization and theoretical calculations, it can be observed that this process can increase the concentration of the OH* intermediate, accelerate the activation process of the Ni site, and ultimately achieve an improvement in overall activity and stability.
