Mesoporous carbon materials derived from sugars (D-fructose, D-glucose, or sucrose) have been prepared using silica aerogel as a template. The silica aerogels were prepared by mixing sugar aqueous solution with the pre hydrolyzed TMOS aqueous solution. The porosity of prepared carbon could be controlled by varying the amount of TMOS, and the specific surface areas were measured as high as 180 m2g-1 with microporosity. With the small amount of TMOS, the surface areas of prepared carbons derived from glucose were further increased up to 312.2 m2g-1 with some mesoporosity. Moreover, the CO2 adsorption capacity also increased up to 3.73 mmol g-1. However, with large amount of TMOS, the prepared carbon exhibited microporosity and low surface areas. |
