Cobalt‐Silicon Coordination‐Induced Nonradical Activation of Peroxymonosulfate for Enhancing the Degradation of Organic Pollutants in Real Wastewater

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 16, 2025

Abstract Nonradical‐driven degradation pathways have emerged as a promising solution for the removal of emerging organic pollutants in complex water matrices. How to construct nonradical systems remains challenge. In this study, novel silicon carbide (SiC)‐supported cobalt single‐atom catalyst (Co/SiC) is developed induce nonradicals activation peroxymonosulfate toward sulfamethoxazole (SMX). The normalized rate SMX reaches 16.425 L·min −1 ·g ·m m , significantly outperforming most reported catalysts. Surface‐bound reactive species dominate process, followed by high‐valent oxo. Experimental and characterization results demonstrate that unique Co‐Si coordination structure facilitated electron transfer, lowered energy barrier formation surface‐bound species, thereby exhibiting superior resistance inorganic ions. seven‐day continuous column experiment, SMX, atrazine, bisphenol A are completely removed from actual secondary effluent, confirming stability effectiveness real wastewater systems. Moreover, acute toxicity treated effluent almost disappears. These highlight potential driving transfer generation nonradicals, offering approach addressing challenges wastewater.

Enhanced Selectivity in PMS Activation via Non-Metal Doping for Efficient ¹O₂ Generation in Emerging Organic Pollutants Degradation

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 30, 2024

The activation of peroxymonosulfate (PMS) to generate singlet oxygen (1O2) for the removal emerging organic pollutants (EOPs) from complex aqueous environments has garnered widespread attention. However, low efficiency and selectivity current PMS 1O2 generation result in suboptimal EOP degradation. To enhance promote non-radical pathway, non-metal heteroatoms with varying electronegativities were introduced disrupt symmetrical coordination structure Fe active sites single-atom catalysts. results showed that, B-Fe1/GLCNs/PMS system, pseudo-first-order kinetic rate bisphenol A (BPA) degradation reached 4.435 min–1, which is 7.4 times higher than that unmodified control group. Experimental theoretical calculations demonstrated doping altered electron density distribution at sites, thereby modulating adsorption configuration HSO5– increasing 1O2. Additionally, EOPs by produced intermediate products lower biological toxicity, strong anti-interference capability. change morphology improved generation. This study provides deep insights into designing high-performance catalysts via regulate electronic a selective pathway.
