Efficient cobalt-based metal-organic framework derived magnetic Co@C-600 Nanoreactor for peroxymonosulfate activation and oxytetracycline degradation

Co-based MOF as an efficient catalyst by peroxymonosulfate activation for degradation of tetracycline: synthesis and performance

“…Methanol (MeOH) was selected as the trapping agent for SO 4 ˙ − and OH˙, tert -butanol (TBA) as the trapping agent only for OH˙, and p -benzoquinone ( p -BQ) and l -histidine ( l -his) as the trapping agents for O 2 ˙ − and 1 O 2 , respectively. 45,46 As shown in Fig. 6a, when p -BQ was present in the system, the TC degradation rate decreased from 91.41% to 83.61%, and the inhibition effect was not obvious, indicating that O 2 ˙ − did not contribute much to the TC degradation process.…”

Fast Degradation of Rhodamine B by In Situ H2O2 Fenton System with Co and N Co-Doped Carbon Nanotubes

“…The active intermediate •OH could be generated from the self-formation process of E-Fenton. As a result, RhB molecules were degraded into intermediates and inorganic small molecules by these various ROSs involved in this system (Equations (5) and (6)) [ 28 , 29 ]. 2H + + O 2 + 2e → H 2 O 2 Co 2+ + H 2 O 2 + H + → Co 3+ + H 2 O + •OH Co + 2Co 3+ → 3 Co 2+ Co 3+ + e → Co 2+ •OH + RhB → intermediates intermediates + •OH → CO 2 + H 2 O + Ions …”

A new 3D 8-connected Cd(ii) MOF as a potent photocatalyst for oxytetracycline antibiotic degradation

“…8a-d); however, the addition of BQ or TBA greatly reduced the photocatalytic efficiency, demonstrating that the key active species in the OXY photocatalytic system were O 2 ˙− and ˙OH, similar to that reported in the literature. 48,49 Hence, O 2 ˙− and ˙OH are the main active species involved in the decomposition of OXY as trapping it by BQ and TBA suppresses the photocatalytic reaction rate (Fig. 8e and f).…”
