A Critical Review on Removal of Gaseous Pollutants Using Sulfate Radical-based Advanced Oxidation Technologies

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(14), P. 9691 - 9710

Published: June 30, 2021

Excessive emissions of gaseous pollutants such as SO2, NOx, heavy metals (Hg, As, etc.), H2S, VOCs, etc. have triggered a series environmental pollution incidents. Sulfate radical (SO4•–)-based advanced oxidation technologies (AOTs) are one the most promising removal because they can not only produce active free radicals with strong ability to simultaneously degrade pollutants, but also their reaction processes environmentally friendly. However, so far, special review focusing on using SO4•–-based AOTs is reported. This reports latest advances in (e.g., Hg, and VOCs) AOTs. The performance, mechanism, species identification advantages/disadvantages these reviewed. existing challenges further research suggestions commented. Results show that possess good development potential pollutant control field due simple reagent transportation storage, low product post-treatment requirements degradation refractory pollutants. Each AOT possesses its own advantages disadvantages terms cost, reliability, post-treatment. Low yield, poor capacity, unclear mechanism/contribution species, unreliable technology high cost still main problems this field. combined use multiactivation strategies overcome defects since it may make up for shortcomings independent technology. In order improve yield enhancement mass transfer optimization design reactor critical issues.

Z-Scheme Heterojunction α-Fe₂O₃/Tubular g-C₃N₄ with C Defects for Photocatalytic Degradation of Microcystin-LR in Water: Generation and Effect of Critical Species ¹O₂

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(8), P. 6272 - 6291

Published: April 10, 2024

Microcystin-LR (MC-LR) is susceptible to degradation by singlet oxygen (1O2) attack due multiple unsaturated olefinic bond sites. In this study, the Z-scheme heterojunction α-Fe2O3/tubular g-C3N4 with C defects (α-Fe2O3/TDCN) was synthesized via hydrothermal and cocalcination methods. The efficient generation of 1O2 realized enhancing photogenerated carrier separation adsorption capabilities used investigate process mechanism MC-LR. results show that rate MC-LR can reach nearly 100% within 60 min under visible light irradiation, α-Fe2O3/TDCN possesses good stability environmental friendliness. relationship between photocatalyst performance analyzed density functional theory (DFT) calculations. Based on probe experiments, LC–MS data, DFT calculations, mineralization dominated analyzed. This study provides a reference for addressing pollution in eutrophic aquatic environments direction specific control mineralization.
