1. A chalcogen-grafted carbon material, wherein the chalcogen-grafted carbon material is a polyaromatic carbon material comprising a polyaromatic fused ring system, and the chalcogen X is covalently linked to the polyaromatic carbon material via C═X bonds on outside rings of said polyaromatic fused ring system and/or C—X—C bonds in the form of 3-membered rings on a surface of said polyaromatic fused ring system, wherein:
the chalcogen is a chalcogen other than oxygen,
C is a carbon atom from the polyaromatic fused ring system, and
wherein the molar ratio of carbon:chalcogen in the chalcogen-grafted carbon material is within the range of from 2:1 to 1000:1.
