The properties of inorganic materials are highly related to chemical composition, crystallographic structures, crystal sizes and growth orientations. Based on topotactic transformation and epitaxial growth, a variety of orientated TiO2 arrays with specific micro- and nano-structures have been grown in addition to the controlled preparation of anatase and rutile titanium dioxide nanoparticles respectively. Benefited from epitaxial growth, some complex nanoarrays with specific interfaces, even with heterostructures have been grown. The relationships between growth orientation and photo-catalysis, and even and lithium storage performance were presented. These TiO2-based materials exhibit adjustable physical and chemical properties.
