Abstract: The eco-friendly electrocatalytic nitrate reduction reaction (NO3RR) at ambient condition is in high demand as a potential replacement for the Haber–Bosch process and for efficient wastewater treatment. The two multicomponent alloys electrocatalysts based on non-noble metals of Co75Si15Fe10 and Co75Si15Fe5Cr5 were synthesized. The samples were characterized and studied by the SEM, EDX, XRD, UV–vis spectroscopy, linear voltammetry, chronoamperometry, and electrochemical impedance spectroscopy. Under the conditions of chronoamperometry, ammonia was synthesized by NO3RR and the values of Faradaic efficiency (FE) and yield rate of NH3 were obtained. The highest FE 58.7% and the largest yield rate of NH3 4.3 μmol h−1 cm−2 at potential − 0.585 V (RHE) in a neutral electrolyte for the Co75Si15Fe10 electrocatalyst for NO3RR. Unexpected for this work was the discovery of an inhibitory effect for an alloy containing a small amount of Cr. This work opens up interesting opportunities for further research of multicomponent alloys for NO3RR.
