Abstract	ZnFe2O4 coupled TiO2 nanotube arrays (ZnFe2O4–TiO2 NTAs) were synthesized by modifying TiO2 nanotube arrays with ZnFe2O4 nanoparticles. Self-organized TiO2 NTAs with a tube diameter of 100 nm and length of 400 nm were prepared by an electrochemical anodization method. ZnFe2O4 nanoparticles were deposited on the surface of TiO2 nanotubes through a facile hydrothermal route. The modification of ZnFe2O4 nanoparticles extended the photoresponse of TiO2 nanotube arrays into the visible light region. Under visible light irradiation, a 12-fold enhancement in photocatalytic activity was achieved using ZnFe2O4–TiO2 NTAs compared with TiO2 NTAs. The enhanced photogenerated electron–hole separation and improved transfer of photogenerated charge carriers were responsible for the increased photocatalytic activity of ZnFe2O4–TiO2 NTAs. This approach provides a simple method for synthesizing a variety of nanoparticle-modified one-dimensional nanomaterials.
