They have good photocatalytic performance, electrocatalytic performance and anti-corrosion properties, and are widely used in energy, environmental protection, life sciences and other fields. Based on the anodic oxidation method, this paper studied the key process parameters for preparing TiO2 nanotube arrays and their influence on nanotube properties, including electrolyte concentration, voltage, anodic oxidation time, etc. At the same time, the morphology, crystallography, and optical properties of the prepared TiO2 nanotube arrays were characterized by SEM, XRD, UV-Vis, etc. Finally, it was found that TiO2 nanotube arrays prepared with HF as electrolyte, voltage of 20 V, and anodic oxidation time of 90 minutes have the best photocatalytic performance.【Key words】TiO2 nanotube arrays; anodic oxidation method; characterization
