Abstract
Chalcogen-grafted carbon material as well as their functionalized forms are described along with processes for their preparation. More specifically, the chalcogen is covalently linked to the carbon scaffold of a polyaromatic carbon via C═X and/or C—X—C bonds. Processes for their preparation include a single thermal treatment without the use of strong acids or anhydrous solvents.
