Chitin-derived biochar with nitrogen doping to activate persulfate for phenol degradation: Application potential and electron transfer pathway in system

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

“…Currently, PS is widely utilized to degrade various organic pollutants, including tetracycline, 37 phenol, and sulfamethoxazole, in advanced oxidation technology. 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.…”

Activation of peroxydisulfate via BiCoFe-layered double hydroxide for effective degradation of aniline

“…The advanced oxidation processes (AOPs) is an effective alternative, among which the SR-AOPs has been the object of recent researches (Giannakis et al 2021). Persulfate, including peroxymonosulfate (PMS) and PDS, can be activated by external energy (e.g., heat (Chen et al 2023), ultraviolet light (Wu et al 2023), ultrasound )), chemical activators (e.g., alkaline (Ren et al 2021), phenol (Fan et al 2023)), transition metals (metal ions ) and heterogeneous catalysts )) and carbonaceous materials (e.g., biochar (Gao et al 2022) and graphene oxide (Yao et al 2023)). Among the above-mentioned methods, transition metal-based multiphase catalysts have attracted much attention for their good catalytic effect, low cost and easy recovery (Liu et al 2023).…”
