本项目以模拟室内香烟烟气产生的PM2.5为研究目标,利用制备合成的碘掺杂二氧化钛(I-TiO2)光触媒喷雾剂进行室内PM2.5的光触媒净化研究.本研究通过烟气、喷雾剂和光照等条件变化的多组对比净化试验,验证了在模拟阳光下所合成的本光触媒喷雾剂针对室内PM2.5净化的可见光活性以及有效性;试验数据结果表明,在最优条件下,加入该喷雾剂180 min后,模拟密封室内环境下的PM2.5的净化率能够超过70%,从而及大地改善了室内环境的空气质量.%Taking PM2.5produced by simulated indoor cigarette smoke as the research goal,photocatalyst purification in indoor PM2.5was studied by using synthetic iodine doped titanium dioxide(I-TiO2)photocatalyst spray. Through a multi group comparative purification test on the conditions change of smoke,spray and light,the visible light activity and effectiveness of the photocatalyst spray synthesized in the simulated sunlight on the indoor PM2.5purification were verified. The experimental data showed that under the optimal conditions,after adding the spray 180 min,the purification rate of PM2.5in the simulated sealed indoor environment can exceed 70%,so that the air quality of the indoor environment was improved.
