Visible-light-driven BiOCl nanoplates were successfully synthesized by polyvinylpyrrolidone (PVP)-assisted hydrothermal method. Effect of PVP weight content on structure, atomic vibration and morphology of the products was investigated. Pure phase of uniform tetragonal BiOCl nanoplates with ± (001) top and bottom and ± (110) side and end exposed surfaces was successfully synthesized in the solutions containing 0.00–1.00 g PVP by hydrothermal method at 180 °C for 24 h. The as-prepared BiOCl nanoplates with different weight contents of PVP adding were studied for photodegradation of rhodamine B (RhB) under visible light irradiation of a xenon lamp. In this research, BiOCl nanoplates with PVP adding exhibit photocatalytic activity higher than BiOCI nanoplates without PVP adding.

PVP 辅助水热法合成的 BiOCl 纳米片的表征及其光催化活性

通过聚乙烯吡咯烷酮（PVP）辅助水热法成功合成了可见光驱动的BiOCl纳米片。研究了PVP重量含量对产物结构、原子振动和形貌的影响。在含有 0.00–1.00 g PVP 的溶液中，通过水热法在 180 °C 下成功合成了具有 ± (001) 顶部和底部以及 ± (110) 侧面和端部暴露表面的均匀四方 BiOCl 纳米片的纯相。研究了制备的具有不同重量含量的 PVP 添加的 BiOCl 纳米片在氙灯可见光照射下对罗丹明 B (RhB) 的光降解。在本研究中，添加 PVP 的 BiOCl 纳米片表现出比未添加 PVP 的 BiOCI 纳米片更高的光催化活性。
