Özet
This study investigated the synthesis, structure, optical properties, and photocatalytic performance of novel Fe-doped zirconium vanadate nano-powders (Fe-doped ZrV2O7 NPs). The nano-powders were synthesized using the hydrothermal method to optimize their photocatalytic efficiency with varying Fe concentrations (0 to 9 mol%). Structural analysis using X-ray diffraction (XRD) revealed that the undoped ZrV2O7 exhibited a monoclinic ZrO2 structure while increasing Fe concentrations introduced new peaks corresponding to the zinc-blende structure of Fe2VO4 and the orthorhombic phase of V2O5. Optical characterization using UV–visible spectroscopy showed that the bandgap decreased from 4.02 eV for undoped samples to 3.11 eV for the sample with nine mol% Fe, improving its light absorption capacity. Photocatalytic experiments were conducted using methylene blue (MB) as the model organic pollutant under visible light irradiation (500 W) at room temperature and neutral pH. Degradation efficiency was evaluated by monitoring the reduction in MB absorbance at 665 nm. The ZrV-9 sample exhibited the highest photocatalytic efficiency, with a degradation rate of 72% within 30 min. Additionally, the catalyst demonstrated excellent stability and recyclability, retaining 90% of its efficiency after five cycles. These findings highlight the potential of Fe-doped ZrV2O7 nano-powders as efficient and durable photocatalysts for organic pollutant degradation under visible light. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
