제목 CO2 adsorption using carbon-coated silica aerogels
초록 Silica aerogels have been prepared using the aqueous solutions of sugar as a template at an ambient temperature and pressure. By the reaction of tetramethylorthosilicate (TMOS) and formic acid, hydrogels were prepared in the presence of sugar. Carbon-coated silica aerogels were obtained successfully by carbonization of silica aerogel containing sugars at 800 oC and ambient pressure under nitrogen atmosphere. The pore structure of silica aerogels were successfully controlled by varying the molar ratio of sugar and TMOS. Carbon-coated silica aerogels have surface areas at a range of 0.6-350 m2 g-1 and show CO2 adsorption capacity at a range of 0.1-1.5 mmol g-1 at room temperature.
