The obtained TiO 2 nanowhiskers were characterized by means of TEM,HRTEM and XRD. The results show that the nanowhiskers are rutile crystals growing along c-axis direction with a length of 100150 nm and a diameter 68 nm. The simple fabrication method of TiO 2 nanowhiskers will promote practical application of 1D TiO 2.展开更多
