The electrocatalytic reduction of NO3 − and its intermediate NO2 − in neutral medium was performed at a Cu-immobilized Pt surface. The voltammetric investigations showed that the bare Cu electrode has little effect on nitrate reduction reactions (NRR) whereas an enhanced catalytic effect (i.e. a positive shift of the peak potential and an increased reduction current) was observed when Cu particles were immobilized onto Pt surface. This study identifies critical mechanisms involved in the enhancement of NRR through improved adsorption thermodynamics and reveals stability aspects of the electrocatalyst. Results indicate that the integration of copper particles significantly enhances the electrocatalytic activity, leading to more efficient nitrate reduction processes. Hence, this work provides a deeper understanding of the mechanism and stability of copper-immobilized platinum electrocatalysts, contributing to advancements in water treatment technologies aimed at reducing nitrate pollution.
