摘要：

Three nanocomposites containing MCM-48-35PEHA-15DEA (35 and 15 as weight percent of amine addition), MCM-48-30PEHA-20DEA and MCM-48-25PEHA-25DEA of mesoporous silica MCM-48 modified by the mixture of pentaethylenehexamine (PEHA) and diethanolamine (DEA) have been synthesized and used to study the adsorption of carbon dioxide (CO2). They are characterized by low angle x-ray diffraction (XRD), Fourier transform infrared (FT-IR) and Brunauer-Emmet-Teller (BET) analysis. MCM-48-35PEHA-15DEA (as optimized adsorbent) shows CO2 adsorption capacity of 0.51 (m center dot mol CO2/g-adsorbent) at 1 bar and 298 K, much higher than CO2 adsorption capacity on polyethyleneimine, pyrrolidinepropyl and polymerized aminopropyl loaded MCM-48.
