Published: April 9, 2025

The existence of indoor volatile organic compound pollution cannot be ignored. main representative pollutant, toluene, poses a serious danger to human health. In this study, BiOX (X = Cl, Br, I) nanophotocatalytic materials were synthesized using straightforward chemical precipitation process. materials' fundamental structure and characteristics examined, it was investigated whether they can remove toluene gas pollutants when put them under sunlight. According the results, within 120 min, degradation rates are ranked as BiOCl > BiOI BiOBr, with BiOBr achieving 16.16%, 28.13%, exhibiting highest efficiency at approximately 56.41%. Toluene entirely broken down fewer intermediates, according conversion rate CO2, product. There also extensive research on photocatalytic mechanism π-bonds benzene ring by active radicals •OH •O2 -. Furthermore, oxygen vacancies holes (h+) worked in concert enhance molecule's adsorption activation, which accelerated breakdown into short-chain molecules, became carbon dioxide water, eventually. These reactions considered environmentally friendly. study gives practical way lessen VOC theoretical evidence for gas.
