Mesoporous Hollow Silica materials with empty interior and well-defined architectures have a high specific surface areas, low density, high loading capacity and can be potentially applied in drug delivery, nano catalyst, gas adsorbents. Studies of mesoporous hollow silica with multiple shells have actively researched to improve physicochemical performance. In this study, we synthesized multi-shell mesoporous hollow silica nanomaterials (MMHS) and prepared amine-impregnated MMHS (A-MMHS) as an adsorbents for CO2 adsorption. MMHS were prepared by sol-gel method using polystyrene as a core material and PEG-PPG-PEG(P123) and cetyltrimethylammonium chloride(CTACl) as dual templates and tetraethylorthosilicate(TEOS) as a precursor. A-MMHS were prepared by impregnation method using tetraethylenepentamine(TEPA) as an amine source. MMHS and A-MMHS characterized by using Transmission Electron Microscopy (TEM), FourierTransform-Infrared spectroscopy (FT-IR), N2-sorption, X-ray Diffraction (XRD) and Gas Chromatography (GC) analysis.
