1. A method for preparation of mesoporous nitrogen-doped carbon comprising forming a composition by solubilizing a nitrogen-containing polymer in an aqueous solution of ZnCl₂and drying the aqueous solution, the method further comprising heating the composition after drying to a temperature to carbonize the nitrogen-containing polymer to form the mesoporous nitrogen-doped carbon.
