Electrochem. upcycling wastewater N such as nitrate (NO3–) and nitrite (NO2–) into an NH3 fertilizer is a promising yet challenging research topic in resource recovery and wastewater treatment. This study presents an electrified membrane made of a CuO@Cu foam and a polytetrafluoroethylene (PTFE) membrane for reducing NO3– to NH3 (NH3) and upcycling NH3 into (NH4)2SO4, a liquid fertilizer for ready-use. A paired electrolysis process without external acid/base consumption was achieved under a partial c.d. of 63.8 ± 4.4 mA cm-2 on the cathodic membrane, which removed 99.9% NO3– in the feed (150 mM NO3–) after a 5 h operation with an NH3 recovery rate of 99.5%. A recovery rate and energy consumption of 3100 ± 91 g-(NH4)2SO4·m-2·d-1 and 21.8 ± 3.8 kWh kg-1-(NH4)2SO4, resp., almost outcompete the industrial NH3 production cost in the Haber-Bosch process. D. functional theory (DFT) calculations unraveled that the in situ electrochem. conversion of Cu2+ into Cu1+ provides highly dynamic active species for NO3– reduction to NH3. This electrified membrane process was demonstrated to achieve synergistic nitrate decontamination and nutrient recovery with durable catalytic activity and stability. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Recommanded Product: Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. The copper-mediated C-C, C-O, C-N, and C-S bond formation is a part of one oldest reaction, emphasizing the Ullmann cross-coupling reaction.Recommanded Product: Cuprichydroxide
