Abstract

Highly efficient Bi₂WO₆–TiO₂ heterostructures are synthesized by means of a hydrothermal method; they have high photoactivity for the degradation of rhodamine B under sunlike irradiation. An interesting synergetic effect between TiO₂ and Bi₂WO₆ leads to an improved charge carrier separation mechanism, causing the excellent photocatalytic performance.
