Titanium dioxide is one of the most widely used metal oxide semiconductors for photoinduced processes because of its comparatively low cost, low toxicity and its ability to resist photocorrosion. Nanoparticulate TiO2 has proven as efficient light-harvesting material for potential use in photocatalytic removal of hazardous industrial byproducts, in nanocrystalline solar cells, photovoltaics and sensors. Manipulating shape and size of TiO2 nanoparticles has gained considerable attention primarily in order to control surface chemistry at nanoscale. Although uniform morphologies and well-defined structures have been studied, there is still lack of full understanding of the interconnection between surface, bulk and electronic properties of nano-TiO2. Herein, we will discuss how size, shape and crystallinity of TiO2 nanoparticles affect their electronic properties, and how interplay between these properties affect tailoring of nano-TiO2 in order to create efficient functional systems.
