Approximate 10 mu m length of mesostructured hollow titania nanotubes with intact configuration was successfully prepared by using needle-like calcium carbonate and octadecylamine as double templates at room temperature in nonaqueous system. During the whole preparation, two parameters i.e. tetrabutoxytitanium/calcium carbonate molar ratio and annealing temperature, Were optimized to obtain titania nanotubes with well-defined tubular morphology and mesoporous Structure in tube walls. The as-prepared samples were characterized by scanning electron microscopy, transmission electron microscopy, broad-angle X-ray diffraction, pore size distribution and Brunauer-Emmett-Teller. The results showed that under optimal experimental conditions i.e. tetrabutoxytitaninum/calcium carbonate molar ratio (50 wt.%) and annealing temperature (773 K). the tube materials exhibited uniform tubular structure with a length of 8-15 mu m and an inner diameter of similar to 400 nm, a wall thickness of similar to 40 nm, a Surface area of 112.2 m(2)/g and a pore volume of 0.18 cm(3)/g. The optimized titania nanotubes Were utilized as a carrier for the immobilized of ibuprofen via a simple adsorption method, It Was found that the loaded drug presented good Sustained release property in three release media, i.e. simulated body fluid, normal saline and pure water.
