N2  - Solid supported ionic liquids can be used to overcome the high viscosity issue of ionic liquids and help increase the efficiency of CO2 removal. In this research, hmimTf2N was impregnated into porous silica dioxide (SiO2) and characterized using Porous and Surface Analyzer, Thermogravimetric Analysis (TGA) and Spectroscopy RAMAN. The CO2 solubility was measured at different pressure at room temperature. The mole fraction of CO2 captured was increased as the pressure increased, and the highest mole fraction was at 40 bar. The mole fraction of CO2 captured at 40 bar for SiO2-hmimTf2N was 0.812 which was higher compared to pure hmimTf2N, with mole fraction of 0.650. Henry's Law Constant (KH) was higher for SiO2-hmimTf2N with 26.8±5.2 bar while for hmimTf2N, the KH was 35.4±3.3 bar. © (2013) Trans Tech Publications, Switzerland.
