Abstract: [Display omitted] • A high-entropy perovskite oxide, La(MnFeCoCuZn) 0.2 O 3 (LMFCCZ), was successfully synthesized. • The performance of NO 3 RR on LMFCCZ outperformed most conventional perovskites. • A novel strategy of using acidic anolyte to provide H+ for NH 3 recovery was introduced. • A nitrogen-potassium compound fertilizer was formed from NO 3 –-N wastewater with paired electrolysis. Electrochemically upcycling wastewater nitrogen, such as nitrate (NO 3 –-N), into a nitrogen fertilizer (e.g., (NH 4) 2 SO 4), holds promise for wastewater treatment and resource recovery. However, two challenges remain: finding an efficient catalyst for electrocatalytic NO 3 –-N reduction into NH 3 (NO 3 RR) and developing a suitable strategy for subsequent NH 3 separation and recovery. In this study, a high-entropy perovskite oxide, La(MnFeCoCuZn) 0.2 O 3 (LMFCCZ), was synthesized and applied for NO 3 RR, illustrating excellent performance with an NH 3 yield rate of 1.5 ± 0.04 mg/(cm2·h) and a FE of 95.0 ± 1.53 % at a potential of −1.1 V vs. RHE. Furthermore, a novel strategy of using acidic anolyte instead of external acid to provide H+ ions for NH 3 separation and recovery was introduced. As a result, paired electrolysis was fully employed to recover nitrogen-based fertilizer from NO 3 –-N without any chemicals addition. Specifically, when acidic anolyte containing 50 mM K 2 SO 4 was served as the absorption liquid, the NH 3 recovery efficiency reached 70.9 ± 3.0 %, and a solid powder containing both nitrogen (N) and potassium (K) was obtained, suggesting the formation of N-K compound fertilizer. This study not only extends the application of high-entropy perovskite oxides in NO 3 RR but also opens a novel avenue for utilization of anodic reactions for nitrogen-based fertilizer recovery.
