Pulsed-Potential Electrochemical Reduction of Nitrate to Ammonia
Pulsed-Potential Electrochemical Reduction of Nitrate to Ammonia This project investigated the electrochemical reduction of nitrate (NO₃⁻) to ammonia (NH₃) using Cu₂O nanoparticles as a low-cost catalyst. Calcined and uncalcined Cu₂O electrodes were tested in an alkaline flow cell and characterized using SEM, XRD, and EDS. Ammonia production was confirmed by UV–Vis and ¹H NMR, with maximum Faradaic efficiencies of 80.12% for calcined Cu₂O and 78.78% for uncalcined Cu₂O, both at −1.6 V vs. Ag/AgCl. Pulsed electrolysis was also explored as an alternative operating strategy.
