Possible mechanism of Photochemical dye degradation

Abstract:

A novel porous titanosilicate/V2O5-ZnO ternary nanocomposite is synthesized by the thermal decomposition method. The structural and morphological properties of the nanocomposites are analyzed by powder X-ray diffraction (PXRD), Scanning electron microscopy-Energy dispersive X-ray analysis (SEM/EDAX), Fourier transform Infrared spectroscopy and Diffuse reflectance Ultraviolet-Visible spectroscopic analysis. The SEM image shows that the composites are having a morphology of Nanorods with spherical shaped particles. The absorption edge in the visible region is shown by UV–Visible spectroscopy. The nanocomposites are expected to increases the charge separation and lifetime of the photogenerated electron-hole pairs, which enhances the photocatalytic degradation of dyes. A plausible structure of the composite is also proposed.
