摘要: Abstract Activated carbon (AC) has been widely used in indoor air quality (IAQ) control for removal of hazardous volatile organic compounds (VOCs). A detrimental effect this adsorption technology is that bacteria multiplied on AC may deteriorate IAQ. In paper, antibacterial nanocomposites with well-dispersed silver nanoparticles (Ag/ACs) were prepared by the attachment Ag + functionalized surface via ion–dipole interactions and subsequent in-situ reduction . The surfaces microporous structures obtained Ag/ACs analyzed means scan electron microscope (SEM) pore size area analysis. Antibacterial tests performed using Escherichia coli ( E. coli ) Staphylococcus aureus S. aureus as model bacteria. activity against airborne toluene capacity further evaluated. It was found introduction significantly improves but slightly reduces ability. can efficiently kill within 100 min without decreasing ability toward toluene.
