摘要： The efficient removal of various pollutants from co-contaminated water is of great significance for maintaining aquatic ecological security. N-doped Ce/Fe bimetallic nano-electrode materials (CeFeNC) were prepared via a one-pot evaporation-induced self-assembly (EISA) method. CeFeNC was used as a cathode to construct an electrochemical coupling system, and nitrate and antibiotics were removed simultaneously by active chlorine generated in situ in water. The redox conversion between Ce3+/Ce4+ promoted the efficient adsorption of NO₃− by oxygen vacancies (Ov), while Fe provided electrons for the reduction reaction. Active hydrogen (H*) promoted N-O bond cleavage and participated in the hydrogenation process. Active chlorine plays a dual role, which can oxidize NH4+ into nitrogen and degrade antibiotics efficiently. Through the electrochemical coupling system, nitrate and tetracycline (TC) were completely removed, with N₂ selectivity as high as 100%. The CeFeNC system demonstrated excellent performance in real seawater and animal husbandry wastewater, along with high stability. This work provides an effective strategy for the simultaneous removal of nitrate and antibiotics in complex water environments.
