| Popis: | Though bulk titanium oxide (TiO2) is widely used in paints, the exciting properties of such material is realized only when it is in nanosize form and hence its nanostructure is being studied intensively all over the world for a large number of applications in the fields like photocalysis, photovoltaic cells, batteries, photonics, ion exchanger, sensors, surface coatings and in textiles, paper and cosmetics as filling material. Therefore, we have prepared TiO2 nanostructure,using a simple technique: thoroughly dispersed and suspended TiO2 powder in deionized water is deposited on different substrates and later reacted in alkaline solution in a sealed Teflon reactor around 100°C for different lengths of time periods, ranging from 6 hrs to 16 hrs. Microscopic study of these samples reveals the formation of a wide variety of TiO2 nanostructures like nanowires, nanotubes nanotapes, Y – and T-junctions. We have also observed “pea-pod” structure for the first time in this study. Possible mechanism(s) for the formation of such structures will be discussed. |
