Magnetically separable bismuth ferrite (BiFeO₃) nanoparticles were fabricated by a citrate self-combustion method and coated with titanium dioxide (TiO₂) by hydrolysis of titanium butoxide (Ti(OBu)₄) to form BiFeO₃@TiO₂ core-shell nanocomposites with different mass ratios of TiO₂ to BiFeO₃. The photocatalytic performance of the catalysts was comprehensively investigated via photocatalytic oxidation of methyl violet (MV) under both ultraviolet and visible-light irradiation. The BiFeO₃@TiO₂ samples exhibited better photocatalytic performance than either BiFeO₃ or TiO₂ alone, and a BiFeO₃@TiO₂ sample with a mass ratio of 1:1 and TiO₂ shell thickness of 50-100 nm showed the highest photo-oxidation activity of the catalysts. The enhanced photocatalytic activity was ascribed to the formation of a p-n junction of BiFeO₃ and TiO₂ with high charge separation efficiency as well as strong light absorption ability. Photoelectrochemical Mott-Schottky (MS) measurements revealed that both the charge carrier transportation and donor density of BiFeO₃ were markedly enhanced after introduction of TiO₂. The mechanism of MV degradation is mainly attributed to hydroxyl radicals and photogenerated electrons based on energy band theory and the formation of an internal electrostatic field. In addition, the unique core-shell structure of BiFeO₃@TiO₂ also promotes charge transfer at the BiFeO₃/TiO₂ interface by increasing the contact area between BiFeO₃ and TiO₂. Finally, the photocatalytic activity of BiFeO₃@TiO₂ was further confirmed by degradation of other industrial dyes under visible-light irradiation.
