Selective production of specific radical species with prolonged lifetime is challenging in advanced oxidation process. Herein, we constructed single-atom Co (SA-Co) catalytic sites confined layered double hydroxide (LDH) for selectively and sustainably generate via peroxymonosulfate (PMS) activation. The negatively charged PMS was stabilized by the positively LDH simultaneously activated nanoconfined sites, resulting oriented-production surface-bonded •OH SO4•− radicals long-term efficiency (up to 48 h), suppressed decomposition self-quenching. Ion competition experiments in-situ spectroscopic studies were applied monitor activation processes. SA-Co-LDH/PMS system outperforms benchmark homogeneous (Co2+/PMS) heterogeneous (Co3O4/PMS) systems degradation emerging organic contaminants (EOCs) lowest consumption highest efficiency.

From complex molecules to harmless byproducts: Electrocoagulation process for water contaminants degradation

Desalination and Water Treatment, Год журнала: 2024, Номер 319, С. 100532 - 100532

As a realistic decontamination strategy and an economically critical component of long-term water surveillance, detailed understanding electrocoagulation processes (ECP) for the remediation contaminants remains vital. When compared to chemical coagulation, ECP delivers greater removal capacities comparable particles does not require any additions. The EC approach generates numerous metal ions in solution by applying electrical current. resultant electro-generated coagulants comprise hydroxides (MeOH-), which function as efficient adsorbent organic pollutants (OPs) inorganic (IOPs), causing formation rise flocs onto electrolyte surface via sweep flotation. For deeper comprehension wastewater, this research critically examines existing trends. It focuses on mechanistic insights electrodes systems, addition myriad catalysts influence various operational parameters reaction mechanism. Ultimately, study builds freshly published uncover varied applications, namely strategies that integrate with treatment process. prospects are promising multifaceted owing its adaptable capabilities, integration possibilities other advantages.
