摘要: Abstract TiO2 nanotube array was prepared by the anodic oxidation method and characterized XRD TEM. The inner pore diameter, wall thickness length of are about 60 nm, 19 nm 1.93 μm, respectively. porosity specific surface area calculated 55% 27.4 m2 g−1, sonophotocatalytic activity evaluated degradation methylene blue. results show that frequency has great effect on synergy between sonolytic photocatalytic degradation. At 27 kHz, synergistic is as high 22.1%. catalyst also shows good recyclability.
