A straightforward hydrothermal method to prepare magnetically recyclable spherical Cu2O@Fe3O4 S-scheme heterojunction for efficient tetracycline removal via visible light-activated peroxydisulfate.
Scrap printed circuit boards were used to prepare a low-cost and efficient heterogeneous peroxydisulfate catalytic activator for the removal of diclofenac and ibuprofen from water at circumneutral pH.
In the PDS/Cu2+ system, bicarbonate can promote the cycling of copper ions with different valence states.
The elaborate design of the peroxydisulfate-based nonradical oxidation process. Nitrogen vacancies enhanced the surface affinity between the catalyst and PDS, and thus, the formation of the key complex (i.e., ACN–PDS*).
The synthesized CoNiFc-MOF catalyst can rapidly activate peroxydisulfate (PDS) to efficiently degrade BPA. The synergistic mineralization of BPA into H2O and CO2 through free radical (·O2−) and non-free radical (1O2/e−) pathways.
