The development of high-performance nanocatalysts for environmental remediation has attracted considerable interest due to their effectiveness in eliminating persistent organic pollutants. In this study, CeO2/Zn2V2O7 hybrid nanocatalysts were synthesized and investigated for their enhanced catalytic efficiency in environmental applications.
The nanohybrids were fabricated using a controlled synthesis method and comprehensively characterized by X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and UV–Visible spectroscopy to evaluate their structural, morphological, and optical properties. Characterization results confirmed the successful formation of a well-integrated hybrid structure with improved surface features and suppressed charge recombination.
The catalytic performance of the synthesized materials was examined through the degradation of model organic pollutants under suitable reaction conditions. Compared to the individual components, the CeO₂/Zn₂V₂O₇ hybrid demonstrated markedly superior degradation efficiency. This enhanced activity is attributed to synergistic effects between the two phases, improved charge separation, and increased generation of reactive oxidative species. Additionally, the catalyst exhibited excellent stability and reusability over repeated cycles without significant loss of activity.
Overall, these findings emphasize the potential of CeO₂/Zn₂V₂O₇ hybrid nanocatalysts as efficient, stable, and sustainable materials for advanced environmental remediation, particularly in wastewater treatment and pollutant degradation processes.
