EcoEnergy, Volume 4, Issue 2, April 2026.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 ...
