CoFe-LDO nanoparticles as a novel catalyst of peroxymonosulfate (PMS) for histidine removal

One-step pyrolysis for the preparation of sulfur-doped biochar loaded with iron nanoparticles as an effective peroxymonosulfate activator for RhB degradation

“…are the focus of water purification for recalcitrant toxic organics. 1 In particular, persulfate-based AOPs are applied to produce these reactive oxidizing species. 2 Peroxymonosulfate (PMS) is more easily activated than peroxydisulfate (PDS) because of its unsymmetrical structure.…”

Degradation of Ciprofloxacin in Water by Magnetic-Graphene-Oxide-Activated Peroxymonosulfate

“…On the other, the increase in MGO could also provide additional active sites to promote the catalytic activation of PMS to generate oxidative radicals such In the Fe 3 O 4 /PMS system, for one thing, Fe 3 O 4 nanoparticles adsorbed a certain concentration of CIP owing to the large specific surface area. For another, SO 4 − • generated from PMS activated by Fe 2+ on the surface of Fe 3 O 4 nanoparticles had a powerful oxidation effect and could remove CIP in water as shown in Reaction (2) [38,39]. However, it is possible that the specific surface area, the stability of dispersion and the catalytic activity of the catalysts may be decreased by the ease of aggregation of Fe 3 O 4 nanoparticles in the solution [40].…”

Enhanced efficiency of refractory organic pollutant degradation over a wide pH range by peroxymonosulfate activated by cobalt-doped FeS

“…The combination of Co 2+ and PMS is the most effective activation strategy compared to other metal ions (Anipsitakis &Dionysiou 2004, Xia et al 2022, Yu et al 2023). In addition, studies have demonstrated that incorporating Co-doping in FeWO 4 (Zhang et al 2023) and Fe 3 O 4 ) can signi cantly enhance the PMS activation, and the presence of Fe can effectively reduce the heavy metal pollution caused by the leaching of Co due to Fe-Co interactions (Liu et al 2020, Luo et al 2021). In natural environments, Co frequently replaces Fe in pyrrhotite owing to its a nity for sulfur and similar ionic radius to iron (Dehaine et al 2021, Savinova et al 2023.…”
