Since the advent of the photocatalytic splitting of water on TiO2 by Fujishima and Honda in 1972 various investigations have been carried out to expand the preponderance application of Titania based nanostructures into various technologies. Recently, there have been tremendous efforts to fabricate highly photoactive titania based nanostructures with appealing properties for heterogeneous catalysis and energy conversion processes. However, the fabrication of titania based nanostructures have been accomplished using complicated preparation methods and expensive materials. The present book outlines versatile, cost-effective precursors and simplified preparation methods that can be used to fabricate titania based nanostructures with improved physicochemical properties. The preparation methods exposed in the current book are fascinating and are anticipated to promote large scale production and commercialization of titania based nanostructures.
