The increasing presence of pharmaceutical contaminants, such as paracetamol, in water sources necessitates the development efficient and sustainable treatment technologies. This study investigates photocatalytic degradation mineralization paracetamol under visible light using nickel-doped titanium dioxide (Ni–TiO2) catalysts synthesized via sol-gel method. were characterized through Raman spectroscopy, UV–Vis diffuse reflectance spectroscopy (UV–Vis DRS), surface area measurements. Ni doping enhanced absorption TiO2, reducing its band gap from 3.11 eV (undoped) to 2.49 at 0.20 wt.% loading, while analysis confirmed incorporation with anatase predominant phase. Ni(0.1%)-TiO2 catalyst exhibited highest activity, achieving 88% total organic carbon (TOC) removal (5 ppm) after 180 min optimal conditions (catalyst dosage, 3 g L−1). Stability tests demonstrated 84% retained efficiency over five cycles, a kinetic rate constant 0.010 min−1. Hydroxyl radicals identified main reactive species. maintained high performance tap water, 78.8% TOC removal. These findings highlight potential cost-effective, light-active photocatalyst for pollutants, promising scalability industrial applications.
