The heterojunction structures of BiOCl/Bi3O4Cl, exhibiting considerable visible-light photocatalytic efficiency, were prepared by a simple wet-chemical process at ambient condition. The prepared nanocomposites were characterized by XRD, TEM, and UV-visible diffuse reflectance spectra. Under visible light (lambda >= 420 nm) irradiation, BiOCl/Bi3O4Cl exhibited an enhanced photocatalytic activity in decomposing 2-propanol (IP) in gas phase and salicylic acid (SA) in aqueous solution, whereas the bare BiOCl and Bi3O4Cl showed negligible activities. It is deduced that the remarkable visible-light photocatalytic activity of the BiOCl/Bi3O4Cl originates from the hole (h(+)) transfer between VB of the Bi3O4Cl and BiOCl semiconductors.
