摘要：

Through anodization in a NH4BF4-containing glycerol solution, TiO2 nanotube arrays were obtained and showed characteristics of both boron-doping and double-layer walled structure. Boron doping inhibited the growth of anatase crystals during the annealing process and enhanced the UV-visible light absorption efficiency of the TiO2 nanotube array. For boron-doped inside, the TiO2 nanotube arrays demonstrated improved photocatalytic activities under both UV and visible light irradiation. This work demonstrates the feasibility of electrochemical preparation of a boron-doped TiO2 nanotube array with double-layer walled structure and its potential application for photocatalysis.
