Nitrate (NO-3) pollution in natural water is severe and brings serious environmental and human health problems. With the rise of electrocatalytic NO-3 reduction, highly reactive and selective electrodes are essential for the electrochem. reduction of NO-3. In this study, a one-step hydrothermal method was used to load Cu and Cu(OH)2 on Ni foam (NF) (Cu(OH)2-Cu/NF) as a cathode. The system′s unique design includes: Cu and Ni can promote the reduction of NO-3 and the generation of active hydrogen atom (H*) as a reducing agent. Then, Cu(OH)2 is beneficial to NO-2 adsorption and promotes the reduction of NO-2 intermediate. Finally, NH+4 is oxidized to N2 by reactive chlorine generated at the anode. The Cu(OH)2-Cu/NF electrode exhibits a 91.5 % conversion of NO-3-N in 90 min, which is 44 times higher than that of NF. Under 2000 mg/L Cl-, NH+4 finally oxidizes to N2 within 360 min, and N2 selectivity is 95.60 %. In addition, the Cu(OH)2-Cu/NF electrode maintained an excellent electrochem. performance after 20 cycles. This study provided a new idea for designing efficient, stable, and inexpensive NO-3 reduction electrodes. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Application of 20427-59-2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The evolution of transition metal catalysts has attained a stage of civilization that authorizes for an extensive scope of chemical bonds formation partners to be combined efficiently. It is clear from the impact copper catalysis has had on organic synthesis that copper should be considered a first line catalyst for many organic reactions.Application of 20427-59-2
