Abstract:

Magnesium-doped tungsten oxide (Mg-WO₃) has emerged as a promising material for advanced photocatalytic applications due to its tuneable nanoscale properties and enhanced catalytic performance. In this study, Mg-WO₃ nanoparticles were synthesized via microwave irradiation method, and their structural, morphological, and optical properties were systematically investigated. The doping of magnesium into the WO₃ lattice was confirmed through X-ray diffraction (XRD) analysis, which indicated lattice distortion and a reduction in crystallite size due to Mg incorporation. Field emission scanning electron microscopy (FE-SEM) revealed a uniform nanostructured morphology with improved surface area, essential for catalytic activity. UV-visible spectroscopy demonstrated a significant bandgap narrowing, enhancing the material's ability to harness visible light effectively. Photocatalytic performance was evaluated using specific target pollutant or reaction with Mg-WO₃ exhibiting superior activity compared to pure WO₃. These findings highlight the potential of Mg-WO₃ nanostructures as efficient photocatalysts for environmental remediation and sustainable energy solutions.
