Jul 1, 2020 · Electrochemically activated PMS significantly enhanced organic pollutants degradation. Compared with PDS, electrochemically activated PMS was easier to generate SO 4 −. Electrochemically activated PMS exhibited strong …

Apr 15, 2023 · In this review, the application of SAC-activated peroxymonosulfate (PMS) or peroxydisulfate (PDS) degradation of organic pollutants is summarized, including new synthesis methods and characterization techniques for SACs, as well as two mechanisms of activated PMS/PDS radical and nonradical degradation of organic compounds, and the future ...

Feb 15, 2018 · This review can provide an overview for the activation and application of PS and PMS for the degradation of emerging contaminants, as well as for the deep understanding of the activation mechanisms of PS and PMS by various methods.

Feb 16, 2020 · PMS and PDS can oxidize alcohols, ketones, phenols, amines, and sulfides without involving radicals. (38,87,172,173)Elbs oxidation and Boyland–Sims oxidation, causing the hydroxylation of phenols and aryl amines, respectively, are primary mechanisms, though specific to PDS in most cases.

As an alternative, activating PDS/PMS is a feasible and green chemical process for 1 O 2 production. Current studies suggest that catalyst is influential to regulate the oxidizing species formed during PDS/PMS-based AOPs.

The objective of this Review is to provide an update on PMS/PDS activation using MOFs as catalysts for organic pollutant degradation. The various types of MOFs based on structure and composition were evaluated for their PS/PMS activation capacities.

Aug 22, 2024 · Fenton-like reactions triggered by peroxydisulfate (PDS) or peroxymonosulfate (PMS) activation were verified to be promising technology for water purification, profiting from the production...

Mar 6, 2025 · Peroxymonosulfate (PMS, HSO 5−) and peroxydisulfate (PDS, S 2 O 82−) are two stable and potent oxidants with redox potentials of 1.82 and 2.01 V, respectively [15, 16]. Their activation during the degradation of organic compounds constitutes an …

Jan 15, 2024 · Modified hydrochar (NHC@Fe), with multiple functional groups and transition metal oxide-containing surface, was successfully synthesized by one-step hydrothermal method. The differences in its catalytic activity for peroxymonosulfate (PMS) and peroxydisulfate (PDS) activation were studied in detail.

May 24, 2024 · Green recycling of Pd and Au is crucial and difficult. Here, we report a peroxydisulfate (PDS)–based advanced oxidation process (AOPs) for selectively recovering Pd and Au from spent catalysts. The PDS/NaCl photochemical system achieves complete dissolution of …
