Abstract
Photocatalysis is an eco-friendly and cost-effective approach for addressing the escalating issue of hazardous organic dye contamination in water bodies, enabling efficient pollutant degradation without generating toxic by-products. Herein, for the first time, tungsten-doped NiFe2O4 (W0.05Ni0.95Fe2O4) nanoparticles were synthesized via a one-step hydrothermal technique. The structural, morphological, and vibrational characteristics were examined using powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), and Raman spectroscopy. The photocatalytic efficiency of NiFe2O4 and W0.05Ni0.95Fe2O4 toward the degradation of Methylene Blue (MB) and Congo Red dyes under visible light irradiation was systematically investigated. Tungsten incorporation remarkably enhanced the degradation efficiency from 76% to 86% for MB dye compared to pristine NiFe2O4. Furthermore, pH-dependent studies revealed superior photocatalytic activity in basic media, achieving up to 98% degradation of MB at pH 14 within 140 minutes, with an increased rate constant of 0.0226 min⁻1. These findings demonstrate that W0.05Ni0.95Fe2O4 nanoparticles serve as highly efficient visible-light-driven photocatalysts, offering great potential for practical applications in advanced wastewater treatment and environmental remediation.
