Structural Features of ZnO@e-HNbWO6 Nanocomposite and Its Photocatalytic Performance

Аннотация

ZnO@e-HNbWO₆ nanocomposite was prepared by exfoliation-restacking method from HNbWO₆ nanosheets and ZnO nanoparticle sol. The as-prepared materials were characterized by means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and UV–Vis diffuse reflectance spectroscopy (UV–Vis DRS). The photocatalytic performance of the prepared materials was evaluated by degradation of Methylene Blue under UV light irradiation. The results show that there is an obvious interaction between host HNbWO₆ nanosheets and guest ZnO nanoparticles. The nanocomposite ZnO@e-HNbWO₆ shows better photocatalytic performance in degradation of Methylene Blue under the UV light irradiation because of the effect on electronic coupling and the transfer of photogenerated electrons in the photocatalytic process due to the synergistic effect between the host and the guest particles.
