Ordered mesoporous carbon materials of the CMK-n (n = 3, 5) family can be obtained by nanocasting pathway using furfuryl alcohol as carbon precursor.

The porosity of CMK-5 consists of two distinctly different pore systems. They occur independently and can therefore be functionalized separately.

Results and Discussion

In the present study, nitric acid oxidation was used to increase the oxygen-containing surface functional groups on the mesoporous carbons. These carbons (or their composites) were further modified via an organic reaction route using SOCl₂ and different amines.

The use of composite material even allow a spatially controlled functionalization of the inner pore system of a CMK-5-type carbon. The choice of the organic molecule allows to manipulate the properties of the carbons and offers therefore the possibility to create ordered mesoporous carbons with desired properties.
