Abstract: The LaNiO3/TiO2 nanotube arrays were prepared by pulse electrodeposition combined with high temperature annealing. The LaNiO3  nanoparticles modified on the TiO2 nanotube arrays had small particle size (< 10 nm), uniform distribution and controllable loading. Some LaNiO3 nanoparticles were deposited inside the TiO2 nanotubes. The UV-visible absorption spectra displayed that the absorption band edge of LaNiO3/TiO2 nanotube arrays was obviously red-shifted as compared with that of TiO2 nanotube arrays, and the visible light absorption was enhanced significantly. The photocatalytic degradation results of rhodamine B (RhB) under visible light showed that the LaNiO3/TiO2 nanotube arrays prepared by pulse electrodeposition for 500 cycles had the optimum photocatalytic activity, and the photocatalytic degradation rate of RhB was 3.5 times that of TiO2 nanotube arrays. Furthermore, the LaNiO3/TiO2 nanotube arrays presented the excellent photocatalytic stability.

Key words: LaNiO3 nanoparticles, TiO2 nanotube arrays, visible-light-induced photocatalysis, rhodamine B
