BiOCl nanostructures including microspheres,microflowers,microplates,and nanoplates,have been synthesized by a simple solvothermal method using bismuth nitrate and sodium chloride as raw materials without adding any additives.Structure and morphology of the products were characterized by powder X-ray diffraction,scanning electron microscopy,and transmission electron microscopy.The results indicated that the as-prepared microspheres and microflowers were composed of nanosheets.Although with different shape and lateral size,the nanoplates and microplales were all single-crystalline plates with exposed {001) facets.It was found that the volume ratio of polyethylene glycol 400 and H_2O in the solvent played a key role in the morphology of the products,and the possible growth mechanism was also discussed.The photocatalytic measurements indicated that the BiOCl samples exhibit good photocatalytic properties towards Rhodamine B.
