Contrarily, soft templates generate the nanostructure through self-assembly of organic molecules. In the case of templated-based synthesis, the synthetic conditions such as mixing ratios, solvents, and temperatures determined the corresponding pore structures of MC. The soft-template synthesis of MC differs from hard-templated method by the self-assembly of organic templates, in which molecules or component moieties are engineered at the molecular level and geometrically systematized in nanospaces through hydrogen bonding, hydrophobic/hydrophilic interactions, and ion pairing. The hard-template approach of Knox and co-workers are being employed today in the synthesis of MC with well-defined mesoporous structure. rigid, spherical MC material with a BET surface area of 400-600 m 2 g -1 , by impregnating a phenol-hexamine mixture as a carbon source into silica gel.
