CuO nanosheets incorporated scrap steel slag coupled with persulfate catalysts for high-efficient degradation of sulfonamide from water

Plasma synthesis of oxygen vacancy-rich CuO/Cu2(OH)3NO3 heterostructure nanosheets for boosting degradation performance

“…The three characteristic peaks of CuO at 529.85, 531.54, and 532.73 eV are attributed to the lattice oxygen (O latt ), oxygen vacancy (O v ), and adsorbed water molecules (O H 2 O ), respectively. 43,44 Characteristic peaks at binding energies of 529.82, 531.65, and 532.51 eV after 15 min of DBD treatment correspond to lattice oxygen (O latt ), oxygen vacancy and hydroxyl oxygen (O v and O OH − ), and nitrogen–oxygen bonds (O NO 3 −), respectively. 41,42 The disappearance of lattice oxygen in CHN-45 and CHN-H with increasing DBD treatment time indicates the formation of pure Cu 2 (OH) 3 NO 3 , consistent with XRD and TEM results.…”

Persulfate-enhanced degradation of propranolol over BiOCl0.5I0.5 under visible light irradiation

“…38,39 Notably, in the photocatalytic process, the addition of PS into the reaction system as an electron acceptor has been demonstrated to effectively reduce the recombination of electrons and holes within the photocatalyst, thereby enhancing the degradation capability for organic pollutants. 40–43 Under the lights, photocatalysts may activate PS to create ˙SO 4 − or to transfer electrons from pollutants, 44 which could further enhance the degradation efficiency of the target pollutants through the synergistic effect of the photocatalysts and PS. For example, Shi et al 45 used a magnetic BiOCl@Fe 3 O 4 catalyst to activate PS for atenolol degradation.…”
