A controlled anion exchange strategy to synthesize Bi2S3 nanocrystals/BiOCl hybrid architectures with efficient visible light photoactivity.

Bi(2)S(3) nanocrystals/BiOCl hybrid architectures with tunable band gaps were synthesized by a controlled anion exchange approach and they displayed highly efficient visible light photoactivities, which is associated with suitable energetics and structural topotactic relationship that can benefit the interfacial charge transfer.
