| Abstract: | The coated PET fabric with atomic ratios of Ti/(Ti+Zn) of 100%, 75%, 50%, 25%, and 0% was successfully prepared via sol–gel process from directly mixing TiO2/ZnO sol. The scanning electron microscopy (SEM) observation, energy dispersive spectroscopy (EDS) and the X-ray diffraction method (XRD) measurements revealed that the microstructural morphology and the crystallization behavior of the composite film were essentially related to the atomic ratio of Ti/(Ti+Zn). The UV irradiated degradation of Methylen blue (MB) solution using the coated fabrics as catalyst showed a tendency of the photocatalytic activity of the film against the value of Ti/(Ti+Zn). Photocatalytic activity was observed for the film with Ti/(Ti+Zn) 25%, which has been attributed to the high degredation of MB. |
