Abstract: TiO2 nanotubes with high specific surface area were prepared by anodic oxidation using Ti plate and Al foil as raw materials. A method of experimental design was introduced. The model parameters were fitted by the full factor experimental design of control voltage and ionic liquid concentration. The TiO2 nanotube film with the largest specific surface area was found at 70 V and 9.25 g/L, which was 51.165 m2/g. Then response surface design was carried out according to the fitting model. The specific surface area of the nanotube film was increased by 3.1 times to 211.125 m2/g. It was found that tiny particles grew on the wall of the nanotube, ranging from 1 to 10 nm, which was consistent with the vertical structure of natural tree trunk branches.
