Efficient degradation of organic pollutants by oxidative radicals is challenging in the complex soil environment because invalid consumption nontarget background substances and generation secondary halogenated pollutants. Nonradical-based oxidation a promising pollutant removal method due to its high selectivity environmental adaptability. Herein, biochar-supported sheetlike CuO (e-CuO@BC) was developed, which exhibited efficient activation peroxydisulfate (PDS) via nonradical pathways. The mechanisms were identified as (i) formation surface-bonding active complexes an outer-sphere interaction between e-CuO@BC PDS (ii) continuous 1O2 cycling Cu(I)/Cu(II) redox couple. In addition, primarily occurred at crystal facet (001) e-CuO occupied Cu atoms well facilitated Cu–O–C bond, induced electron-rich centers around CuO. Two species from activation, including 1O2, showed highly selective toward Moreover, mineralization effective inhibition on toxic byproducts (i.e., organics) indicated intermediate final products. This study provides comprehensive understanding heterogeneous process PS catalyst for removal.

Heterogeneous Photocatalytic Activation of Persulfate for the Removal of Organic Contaminants in Water: A Critical Review

ACS ES&T Engineering, Journal Year: 2022, Volume and Issue: 2(4), P. 527 - 546

Published: March 8, 2022

Heterogeneous photocatalytic persulfate (PS) activation technologies are being intensively studied for water treatment due to their friendly environmental benefits and photosynergistic effect in comparison with traditional PS systems. Previous reviews have summarized diverse methods the role of light systems, but it is still urgent provide a comprehensive review on deep understanding rational design heterogeneous PS-based advanced oxidation processes (AOPs). This intends thoroughly address in-depth fundamentals mechanisms PS-AOPs. Challenges improvement strategies PS-AOPs also critically discussed. On basis detailed survey published studies, PS-AOPs, including Fe-based, TiO2-based, other metal based, bimetallic, metal-free carefully clarified. Finally, engineering implications prospects enumerated developing efficient environmentally treatment. It expected that this will motivate researchers construct novel promising
