摘要
Anatase single-crystal nanotubes were obtained using an in situ templated method. First, highly ordered titania arrays were formed through an anodization process in H3PO4 electrolytes containing 0.5 wt% HE Under optimized conditions titania nanotubes with a diameter of up to 100 nm and a length of up to 1.1 mu m were prepared. Second, the crystallization and stability of the titania nanotubes were studied in air at elevated temperatures. Anatase single-crystal nanotubes were fabricated after annealing the sample in air at 450 degrees C. The anatase single-crystal structure was verified by selected area diffraction pattern and HRTEM images.
