摘要：
A unique flowerlike Bi2O2(OH)NO3/BiOCl nanocomposite was successfully synthesized and characterized by XRD, SEM, TEM, N-2 adsorption-desorption and XPS. The Bi2O2(OH)NO3/BiOCl nanocomposites display improved photocatalytic activity than pure Bi2O2(OH)NO3 and BiOCl. Spectroscopic results and photoelectrochemical analysis revealed that the improved photocatalytic activity is mainly attributed to the enhanced photogenerated electron-hole separation in Bi2O2(OH)NO3/BiOCl heterostructure and synergistic effect between two component. Among them, 9% BON-BOC exhibits the best photodegradation activity of dye solution with 92% of degradation in 100 min. In addition, the photocatalytic mechanism were also investigated in detail.
