Preparation, characterization and photocatalytic performance of rntile TIO2 nanowire arrays via a novel hydrothermal process

摘要：

The single crystal rutile TiO2 nanowire arrays with flat tetragonal crystallography plane were successfully synthesixd via a novel hydrothermal method. The prepared samples were characterisd by Xray diffraction (XRD) and scanning electron microscopy (SEM). The photocatalytic activities of the TiO2 nanowires were determined by degradation of methyl orange molecules in water under UV-light irradiation. The results indicated that the TiO2 nanowires were rutile phase. The reaction temperatures, pH values and time did not change the crystal structures, while the morphologies of nanowire arrays changed. The photocatalytic experiments revealed that different synthesis conditions can affect the photocatalytic activity of the sample under UV-light irradiation.
