A facile growth procedure by low-pressure chemical vapor deposition (LCVD) has been developed to obtain single crystal TiO2 nanorods on Ni-coated Ti substrate.The morphology of samples is critically depended on the growth temperature.Within a range of growth temperature of 700~800℃,single crystal TiO2 nanorods are obtained in large-scale.The nanorods are high purity rutile with a preferential orientation [110].
