摘要：

The evolution of morphology and heterostructure of BiOCl was investigated during an in situ oxidation reaction. Morphology and structure transformation of regular 2D nanoflake, 0D nanosphere or 3D nanoflower was achieved by adjusting the ratio of reagent concentration or reaction temperature, respectively. The enhanced photocatalytic degradation ability and the photocurrent intensity of BiOCl nanomaterials may be attributed to the improved degree of crystallinity and the formation of Bi/BiOCl heterostructure. The photocurrent density of Schottky battery was increased due to enhancing the optical pathway and assisting during charge separation. Crystallinity also contributed to the improvement of the photoelectric conversion efficiency and reduction of the recombination rate of photogenerated electron-hole pairs.
