Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

Advanced Science, Volume 13, Issue 42, 28 July 2026.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.

MXene–MOF Hybrid Nanocomposites: Emerging Platforms for Sustainable Wastewater Treatment

EcoMat, Volume 8, Issue 7, July 2026.
This review presents MXene–MOF hybrid materials for advanced water purification. By integrating the high conductivity and hydrophilicity of MXenes with the tunable porosity of MOFs, these hybrids demonstrate superior performance in adsorption, photocatalysis, and electrochemical degradation.

Chloride Coordination‐Engineered Fe–NC Catalyst for Directed Singlet Oxygen Generation Through Peroxymonosulfate Activation

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

Tetracycline degradation by dual-frequency ultrasound combined with peroxymonosulfate

Ultrasonics Sonochemistry
Tetracycline has received a great deal of interest for the harmful effects of substance abuse on ecosystems and humanity. The effects of different processes on the degradation of tetracycline were compared, with dual-frequency ultrasound (DFUS) in combination with peroxymonosulfate (PMS) being the most effective for the tetracycline degradation.
