Mesoporous Hollow Silica materials have a high specific surface areas and high thermal stability and can be potentially applied in drug delivery, nano catalyst, gas adsorbents. In this study, we synthesized multi-shell mesoporous hollow silica nanospheres(MMS) and prepared CO2 adsorbents to confirm the ability as gas adsorbents. CO2 adsorbents were prepared by impregnation methods using tetraethylenepentamine(TEPA) as an amine source. MMS were prepared by sol-gel method using polystyrene as a core material and poly(ethyleneglycol)-block-poly(propyleneglycol)-block-poly(ethyleneglycol)(P123) and cetyltrimethylammonium chloride(CTACl) as dual templates and tetraethylorthosilicate(TEOS) as a precursor. MMS characterized by using FourierTransform-Infrared spectroscopy (FT-IR), N2-sorption, X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and Gas Chromatography (GC) analysis.
