Abstract
It is known that loaded some metals on the TiO2 surface facilitate their organic decomposition properties. In this study, Cu and Fe were loaded in the TiO2 films. The concentration of Cu- and Fe- loadings was varied from 0.2 to 5wt%, respectively. Their hydrophilic and Methylene blue decomposition properties were evaluated. The hydrophilic property was evaluated by a contact-angle measurement method. We also tried to investigate the difference between Cu loading and Fe loading by using XPS analysis and photo absorbance measurement. We found that pure TiO2 showed best properties in this study. It was shown that the 5wt% of Cu- and Fe- loadings deteriorated the photocatalytic properties.
