摘　　要：本研究制备了碘掺杂二氧化钛(I-TiO_2)的光触媒喷雾剂,以香烟烟气中的PM_(2.5)物质为目标物,研究了在模拟室内密封和太阳光照环境中,本光触媒喷雾剂对于PM_(2.5)的净化效用。结果表明,本光触媒喷雾剂能较为明显的降低室内的PM_(2.5)含量,在180 min后,PM_(2.5)净化效果可达到70%以上。In this study, photocatalyst sprays of iodine-doped titania （I-TiO2） were prepared. The PM2.5 material in cigarette smoke was used as the target. In the environment of simulated chamber and sunlight, the photocatalyst For the purification effect of PM2.5. The results show that the photocatalyst can significantly reduce the PM2.5 content in the room, and after 180 min, the purification effect of PM2.5 can reach more than 70%.
