- 요약Electrocatalytic reduction of nitrate has merged as one of the promising sustainable approach to remove the excess nitrate in wasterwater. Electrocatalysis enables the conversion of pollutants into valuable chemicals using clean energy. Traditionally, catalyst development relies on trial-and-error methods, but a rational design strategy necessitates a deeper understanding of the nitrate reduction process. Currently, surface-specific mechanistic insights are largely derived from theoretical models, and there is no direct experimental evidence at the molecular level. A comprehensive understanding of the reaction pathway would significantly enhance the knowledge of electrocatalysis of nitrate reduction.In this dissertation, attenuated total reflectance surface enhanced infrared absorption spectroscopy(ATR-SEIRAS) is used to directly probe the intermediate species at the surface of a Cu/Ni alloy film. The identity and concentration of these intermediates are monitored under various electrochemical conditions, allowing their correlation with applied potential and time. This work provides the first real-time, surface specific experimental evidence for the reaction mechanism of nitrate reduction on metal alloys, establishing a systematic approach and methodology applicable to similar catalytic systems.
