Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

open access: yesAdvanced Science, EarlyView.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.

Magnetic Pinecone Biochar‐Activated Peroxymonosulfate for Efficient Sulfamethoxazole Degradation: Performance, Mechanism, and Toxicity Analysis

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Fe‐Free Photocatalysis‐Self‐Fenton System for Ultraefficient Water Purification Enabled by Carbon Nitride With Strong Built‐in Electric Field

open access: yesEcoEnergy, EarlyView.
This study reports a photocatalytic H₂O₂ production rate of 14.9 mmol g⁻¹ h⁻¹, representing a 22.2‐fold enhancement. Additionally, the Fe‐free PSFs achieved complete degradation of 100 mg·L⁻¹ tetracycline within 10 min across a wide pH range. ABSTRACT Photocatalytic‐self‐Fenton system (PSFs) hold great promise for water purification through in situ ...
