采用无溶剂法合成了BiOI纳米片和BiSI纳米棒。研究了薄膜的相组成、形貌、生长取向以及从片晶到棒晶的转变。几个实验事实表明，BiOI纳米片和BiSI纳米棒的生长方向是由它们相应的晶体结构基序引导的。测量了BiOI和BiSI的光学带隙分别为1.97和1.61 eV，并初步测量了BiOI片层的可见光光催化活性。
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.
