Synthesis of a high-surface area VO/TiO-SiO catalyst and its application in the visible light photocatalytic degradation of methylene blue.

In the present study, we synthesized several high-surface area VO/TiO-SiO 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.
