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.
