Intrinsically sulfur- and nitrogen-co-doped carbons from thiazolium salts.

Carbon materials that are intrinsically co-doped with nitrogen and sulfur heteroatoms are synthesised by facile annealing of nitrile-functionalised thiazolium salts. Extremely high degrees of doping are achieved, especially for sulfur. The method further allows for direct tuning of the amounts of both N and S, establishing a new synthetic pathway in the emerging field of S-doped carbon materials.
