Hydrothermal synthesis of Bi6O6(OH)(3)(NO3)(3)center dot 1.5H(2)O/BiOCl heterojunction with highly enhanced photocatalytic activity

摘要

In this study, an efficient Bi6O6(OH)(3)(NO3)(3)center dot 1.5H(2)O/BiOCl heterojunction was prepared by a facile hydro thermal method, Bi6O6(OH)(3)(NO)(3)center dot 1.5H(2)O nanoparticles with an average size of approximately 10 nm were grown uniformly in situ on the plates of BiOCl. The modification of Bi6O6(OH)(3)(NO3)(3)center dot 1.5H(2)O effectively improves the photocatalytic activity of BiOCl for the degradation of rhodamine B (RhB). The enhancement of the photocatalytic activity could be attributed to the increased light harvesting ability, decreased charge resistance, and suppressed recombination of photoinduced electron-hole pairs in Bi6O6(OH)(3)(NO3)(3)center dot 1.5H(2)O/BiOCl heterojunction.
