Abstract

Boron and phosphor co-doped TiO2 nanotube arrays (BP–TNTs) were prepared in an electrolyte containing triethyl borate and tributyl phosphate via an anodization process on a Ti sheet, and were characterized by the field-emission scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and UV–Vis diffusion reflectance spectroscopy. The photoelectrochemical properties and photocatalytic activities of obtained-samples were tested under visible light irradiation. The results showed that the photoelectrochemical and photocatalytic activities of B–TNTs, P–TNTs and BP–TNTs were higher than those of pure TiO2 nanotube arrays (TNTs). The synergistic effect of B and P co-doping was absent.
