| Mesoporous carbons are applied in many fields as adsorbents, nanoreactors, catalyst supports and electrode materials. As the hydrophobic nature of highly mesoporous carbons is disadvantageous with respect to the access of water molecules, their surface chemistry became a key-property in many below mentioned applications. The surface chemistry of glycerol-derived mesoporous carbons, with a hexagonal packing, have been investigated in the present paper. This study reports the EPMA, FT-IR Spectroscopy, Boehm titration results, and some sorption measurements on the carbons resulted from templating siliceous nanoreactors. The obtained results showed that their surface is rich in surface functional groups that are responsible for sorption process of various substrates. A great ability for methylene blue removal (677 mg/g for 1.25C sample) and a moderate adsorption capacity for phenol (58 mg/g for IC sample) have been obtained, without any chemical functionaization. Various carbon precursor/silica ratios in the carbon synthesis were used and investigated from this point of view. |
