摘　　要：Well defined BiOI nanolamellas and BiSI nanorods have been synthesized by a solventless method. The phase identity, morphology, growth orientation, and conversion from lamella to rod have been investigated. Several experimental facts suggest that the growth orientations of BiOI nanolamellas and BiSI nanorods are guided by their corresponding crystal structure motifs. The optical band gaps of BiOI and BiSI are measured to be 1.97 and 1.61 eV, and the visible light photocatalytic activity of BiOI lamellas is primarily measured.Well defined BiOI nanolamellas and BiSI nanorods have been synthesized by a solventless method.
