Abstract
Semiconductor heterostructures are of great interest in a wide range of applications. In this work, we design and synthesize a novel heteronanostructure with controlled relative composition, i.e., BiVO<sub>4</sub>/Bi <sub>2</sub>S<sub>3</sub> hollow discoid-like particles with mesoporous shell. The synthesis involves a facile anion exchange process by reacting pre-synthesized BiVO<sub>4</sub> discoid-like particles with Na<sub>2</sub>S in an aqueous solution. Benefiting from the unique structural features and the formation of heterostructure, the as-prepared BiVO<sub>4</sub>/Bi <sub>2</sub>S<sub>3</sub> hollow discoids exhibit significantly enhanced photoelectrochemical current response and photocatalytic activity for reduction of Cr<sup>VI</sup> under visible-light illumination. Unique features: Uniform heterostructured BiVO<sub>4</sub>/Bi<sub>2</sub>S<sub>3</sub> hollow discoids with mesoporous shell are synthesized by a facile anion exchange reaction of BiVO<sub>4</sub> discoids in aqueous Na<sub>2</sub>S solution. Because of their heterostructured nature they exhibit significantly enhanced photocurrent response and photocatalytic activity for reduction of Cr<sup>VI</sup> under visible-light illumination. © 2014 WILEY-VCH Verlag GmbH & Co.
