Synthesis of a high-surface area V₂O₅/TiO₂-SiO₂ catalyst and its application in the visible light photocatalytic degradation of methylene blue.

ABSTRACT: In the present study, we synthesized several high-surface area V₂O₅/TiO₂-SiO₂ catalysts (vanado titanium silicate, VTS). The synthesized materials were characterized by PXRD, FE-SEM/EDAX, TEM, FTIR, UV-Vis, XPS, fluorescence and photocatalytic activity studies. The small-angle powder X-ray diffraction pattern shows that the 110 and 200 planes are merged to become a single broad peak. Field-emission scanning electron microscopy shows that the titanosilicate is spherical in shape and V₂O₅ has a hexagonal rod-shaped morphology. The presence of various metal ions, such as V, Ti, Si and O, was observed by energy dispersive X-ray analysis and X-ray photoelectron spectroscopy. The transmission electron microscopy image shows clear
