Abstract
V2O5/TiO2 nanocomposites were synthesized via sonochemical and hydrothermal process. At first, titanium dioxide (TiO 2) nanopowders were synthesized by sonochemical process using titanium isopropoxide as a titanium source. Meanwhile, hydrothermal process was carried out to modify the structure of commercial V2O5 powder to be nanorod-like structure V2O5 with increasing specific surface area. Structural and morphological properties of the composites were characterized by XRD and SEM, respectively. The XRD results indicated that the crystalline of the composites corresponds to anatase and orthorhombic structures of TiO2 and V2O5, respectively. The significant variation of charge storage properties of the nanocomposites under ultraviolet irradiation were obtained by varying V2O5 content in the composite. Results suggest that V2O5 loaded into the nanocomposite play a key role as a storage material of photoelectron generated by TiO2 illuminated under ultraviolet. © 2013 IEEE.
