Titanium dioxide(TiO2) is an important functional material for photocatalytic applications due to its outstanding photocatalytic characteristics. The TiO2 particle shape plays the significant role in photocatalytic activity. For example, one dimensional structures such as nanowires and nanorods can enhance the separation and offer a pathway for oriented charge carrier transport. Three dimensional structures such as flower-like and coral-like show the extremely large surface area comparing to other structures. In this study, we synthesize TiO2 colloidal nanoparticles which have various shapes by applying various experimental conditions. We manufacture TiO2 nanoparticle films on glass substrates by applying self assembly techniques. Moreover, photocatalytic investigations for the TiO2-coated glass are carried out by measuring photodecomposition of methylene blue. Films are analyzed by XRD, FESEM, AFM and UV-Vis spectroscopy. |
