Abstract
A novel, hydrothermal and hard-template-free method was developed for the first time to grow oriented, single-crystalline monoclinic VO2 (B) flower-like nanorod films on transparent conductive fluorine-doped tin oxide (FTO) substrates. The length and morphology of the nanorods can be tuned by changing the growth parameters, such as growth time and initial precursor concentration. The flower-like V2O5 films were obtained after post-calcination treatment of VO2 (B) films. The photocatalytic activity of V2O5 films was investigated by the degradation of methylene blue (MB) under UV and visible light. The prepared V2O5 film exhibited good photocatalytic performance (74.6% and 63% under UV and visible light for 210min, respectively) and more practical application in industry.
