摘要：

A novel narrow-band photocatalyst, BiCu2VO6, was successfully synthesized by modulating the band structure of the semiconductor. BiCu2VO6 exhibits higher activity for O2 evolution under visible-light illumination. The picture shows the incident photon-to-current efficiency (IPCE) for a BiCu2VO6 particulate thin-film electrode (■). (Graph Presented). © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
