Oxidative polymerization versus degradation of organic pollutants in heterogeneous catalytic persulfate chemistry

Water Research, Journal Year: 2024, Volume and Issue: 255, P. 121485 - 121485

Published: March 18, 2024

Catalytic polymerization pathways in advanced oxidation processes (AOPs) have recently drawn much attention for organic pollutant elimination owing to the rapid removal kinetics, high selectivity, and recovery of carbon from wastewater. This work presents a review on regimes AOPs their applications wastewater decontamination. The mainly highlights three critical issues reactions induced by persulfate activation (Poly-PS-AOPs), including heterogeneous catalysts, pathways, properties substrates. dominant influencing factors selection reactive oxygen species, substrates are discussed detail. Moreover, we systematically demonstrate merits challenges Poly-PS-AOPs upon degradation polymer synthesis. We particularly highlight that technology could be promising treatment industrial containing heterocyclic organics synthesis polymers polymer-functionalized materials environmental energy applications.

Synthesis of Fe–Mn-Based Materials and Their Applications in Advanced Oxidation Processes for Wastewater Decontamination: A Review

Industrial & Engineering Chemistry Research, Journal Year: 2023, Volume and Issue: 62(28), P. 10828 - 10848

Published: July 3, 2023

With the development of industry and agriculture, increasingly serious problems environmental pollution water quality deterioration that affect human health need to be solved. Materials containing both Fe Mn, two most abundant metal elements, have been widely used for wastewater decontamination since they are nontoxic, low-cost, easy prepare, highly efficient. This review systematically summarizes synthesis methods Fe–Mn-based unloaded materials (such as spinel-type, perovskite-type, layered double hydroxides, metal–organic framework, its derivatives) loaded (carbon materials, oxides, other materials). Furthermore, progress application in fields Fenton, photo-Fenton, electro-Fenton, persulfate, sulfite catalysis processes analyzed. Different activation mechanisms such radical pathways nonradical (like direct electron transfer pathways, singlet oxygen, high valence metals, etc.) described. Finally, potential remediation is clarified future research directions pointed out. It expected this can provide new inspiration subsequent on Fe–Mn based treatment.
