In this study, the guanidine compound, 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) was impregnated to three kinds of silica to prepare $CO_2$ adsorbents, and the $CO_2$ adsorption and physicochemical properties of the resulting adsorbents were investigated. The TBD amount of impregnation was changed and its effect on adsorption capacity and characteristics were studied. The physicochemical properties of TBD-impregnated silica were evaluated with $N_2$ adsorption/desorption, FT-IR, elemental analysis, and thermogravimetric analysis. The TBD-impregnated silica lowered the surface area and pore volume, and the increased impregnation amount of TBD made them further decrease. When TBD was 6 mmol/g, the $CO_2$ adsorption capacity was the highest at 7.3 wt%, and the adsorption capacity decreased due to the blocking phenomenon when the TBD amount increased.
