Abstract In this paper, we used different ways to prepare MCM-41 obtaining variant structure and investigated the effect of mesoporous structure of MCM-41 on the CO2 adsorption capacity. The resultant samples were characterized by small angle X-ray power diffraction (XRD), high resolution transmission electron microscope (HRTEM), N2 adsorption/desorption, thermal gravimetric analysis (TGA) for the CO2adsorption performance. The results showed that the sample had large specific surface and volume, which was synthesized with sodium silicate and sulfuric acid as raw material. The adsorption capacity of the sample loaded 50% PEI reached 269.3 mg/g. It was 3.4 times as high as the adsorption capacity of the pure PEI in the same conditions. Loading in the MCM-41 which had a large surface area and pore volume, PEI could be scattered fully and amino of PEI could be utilized fully.
