Claim 19:
20. A process for the preparation of a chalcogen-grafted carbon material, comprising the steps of:
(a) disposing a polyaromatic carbon material in a first compartment and a chalcogen in a second compartment, where the first and second compartments are connected to allow gaseous exchange without direct physical contact between the polyaromatic carbon and chalcogen; and
(b) simultaneously heating the first compartment at a first temperature and the second compartment at a second temperature;
wherein the first temperature is higher than the second temperature and wherein the second temperature allows the sublimation of the chalcogen;
wherein said chalcogen is a chalcogen other than oxygen.
