Porous silica spheres as indoor air pollutant scavengers.
نویسندگان
چکیده
Porous silica spheres were investigated for their effectiveness in removing typical indoor air pollutants, such as aromatic and carbonyl-containing volatile organic compounds (VOCs), and compared to the commercially available polymer styrene-divinylbenzene (XAD-4). The silica spheres and the XAD-4 resin were coated on denuder sampling devices and their adsorption efficiencies for VOCs evaluated using an indoor air simulation chamber. Real indoor sampling was also undertaken to evaluate the affinity of the silica adsorbents for a variety of indoor VOCs. The silica sphere adsorbents were found to have a high affinity for polar carbonyls and found to be more efficient than the XAD-4 resin at adsorbing carbonyls in an indoor environment.

Abstract Uniform colloidal monodispersed silica nanoparticles were synthesized via stöber method using ammonia as a basic catalyst. Field Emission Scanning Electron Microscope (FESEM) was confirmed the homogeneous nanospheres. The decrease of TEOS concentration (0.067 to 0.012 mol L-1) and an increase of H2O concentration (3 to 14 mol L-1) at 14 mol L-1 NH3 fixed accelerated the rate of h...
متن کاملSynthesis of CuO and Cu3N Nanoparticles in and on Hollow Silica Spheres
Copper oxide nanoparticles within hollow mesoporous silica spheres were prepared by binding/adsorbing Cu2+ or [Cu(NH3)4(H2O)2]2+ ions on the surface of carbon spheres, followed by formation of a mesoporous silica shell by sol-gel processing and calcination in air. The CuO nanoparticles can subsequently be converted into Cu3N nanoparticles by nitridation with ammonia. The effect of the different...
