TiO2-SiO2-Fe2O3 heterojunction using the ceramic technique was used in this study to investigate its effectiveness as a photocatalyst for Rhodamine B (RhB) dye degradation. Structural, optical, and morphological characterizations of synthesized materials were carried out by X-ray diffraction (XRD), photoluminescence analysis (PL), scanning electron microscopy (SEM-EDS), diffuse reflectance spectroscopy (DRS) calculate gap energy. In addition, degradation rate around 97% obtained at pH 8, an initial RhB concentration 10 mg·L−1, TS-1F semiconductor dosage 1 g·L−1, reaction time 210 min. The ability photocatalysis degrade different ratios, pH, with/without H2O2 aqueous media evaluated under UV light, visible light (250 W), sunlight. When it comes W) sunlight, respectively, influence n–p junction showed promising results RhB. contrast, there no discernible photocatalytic activity which proves that absorbance switched from visible, demonstrating decrease band Additionally, procedure’s cost-effectiveness reusability through economic revealed material interesting terms both cost sustainability.

Synthesis and Characterization of a Novel Sol–Gel-Derived Ni-Doped TiO2 Photocatalyst for Rapid Visible Light-Driven Mineralization of Paracetamol

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(7), P. 530 - 530

Published: March 31, 2025

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.
