Fabrication of titanate nanowires with different dimensions

Titanate nanowires were fabricated by the reaction of titania particles in a highly concentrated KOH aqueous solution at 150 °C for more than 20 h followed by the rinsing of the resultant compound with a 0.1 M HCl aqueous solution and purified water. The diameter and length of the titanate nanowires can be controlled by using titania powders with different crystalline phases and particle sizes. The crystalline phase in the titanate nanowire was considered to be a hydrated titanate.
