Abstract This study proposes a novel, cost‐effective nano CoFe 2 O 4 ‐decorated halloysite nanotubes (CoFe /HNT) catalyst, which effectively degrades the antibiotic ornidazole (ONZ) through peroxymonosulfate (PMS) activation. By using simple and economical preparation method, ultra‐low amounts of are uniformly loaded onto HNTs, significantly improving activity stability catalyst. The experimental results show that /HNT+PMS system can almost completely degrade ONZ within 1 h, with good pH adaptability resistance to anion interference. synthesis process low cost /HNT make it highly practical for large‐scale applications. Mechanism studies have shown synergistic effect between Co Fe greatly improves activation efficiency PMS, generating reactive oxygen species (such as ) play key role in degradation. work not only elucidates mechanism, but also provides insightful information advanced oxidation processes (AOP). indicate practicality importance catalyst treating harmful pollutants water, supporting effective sustainable water purification technologies. In addition, emphasizes elasticity this innovative managing various pollutants, indicating its broad potential environmental

Single-atom catalysts activate persulfate to degrade emerging organic contaminants in aqueous environments

Water Science & Technology, Journal Year: 2024, Volume and Issue: 90(3), P. 1047 - 1069

Published: July 12, 2024

Single-atom catalysts (SACs) exhibit outstanding catalytic activity due to their highly dispersed metal centers. Activating persulfates (PS) with SACs can generate various reactive oxygen species (ROS) efficiently degrade emerging organic contaminants (EOCs) in aqueous environments, offering unique advantages such as high reaction rates and excellent stability. This technique has been extensively researched holds enormous potential applications. In this paper, we comprehensively elaborated on the synthesis methods of limitations, factors influencing performance SACs, including center characteristics, coordination environment, types substrates. We also analyzed practical considerations for application. Subsequently, discussed mechanism activating PS EOCs degradation, encompassing adsorption processes, radical pathways, non-radical pathways. Finally, provide prospects outline our vision future research, aiming guide advancements applying technique.
