Photodegradation of diclofenac in aqueous media <i>via</i> a HO˙ radical pathway using CeO₂/g-C₃N₄ heterojunction under visible light: experimental and computational insights.

ABSTRACT: Diclofenac (DCF), a widely prescribed nonsteroidal anti-inflammatory drug (NSAID), is frequently detected in aquatic environments due to its extensive usage and poor removal by conventional wastewater treatment technologies. Among various remediation strategies, photocatalysis has emerged as a cost-effective and sustainable approach for the degradation of such persistent pharmaceutical pollutants. In this study, a CeO₂/g-C₃N₄ heterojunction photocatalyst was synthesized and optimized for the visible-light-driven photodegradation of DCF in aqueous media. Under optimized conditions (catalyst dosage: 0.5 g L^-1, initial pH: 6.8, light source: 200 W Xe lamp with λ > 420 nm cutoff filter), the composite achieved 92.6% DCF removal and 75% TOC rem
