Abstract
LaFeO3nanoparticle-coupled TiO2nanotube arrays (LaFeO3/TiO2NTs) was synthesized by loading LaFeO3nanoparticles on TiO2NTs using an ultrasound-assisted impregnating method. LaFeO3nanoparticles were first prepared by stearate precursor and then deposited on the TiO2NTs which were grown on Ti foils by electrochemical anodization. The heterostructured LaFeO3/TiO2NTs exhibited a higher visible light photocatalytic activity than TiO2NTs and excellent photochemical stability. The feasibility of charge transfer in LaFeO3/TiO2NTs was confirmed by PL and EIS. The enhanced photocatalytic activity of LaFeO3/TiO2NTs is mainly attributed to the heterojunction between LaFeO3and TiO2NTs which promotes the transfer and separation of photogenerated charges. ? 2017 Elsevier B.V.
