Abstract
A method for preparing a nitrogen/sulfur-rich activated carbon, of exceptionally high surface area and microporous nature, the method comprising: preparing an aromatic oligomer including a heteroatom using an oxidative polymerization solution, wherein the oxidative polymerization solution comprises a first oxidizer and an organic solvent; mixing the oligomer with an activating agent to obtain a mixture; subjecting the mixture to carbonization and activation in a tube furnace; holding the mixture at a set temperature; cooling the mixture to room temperature to obtain a carbon material; purifying the carbon material by washing; washing the carbon material with water and methanol; drying the carbon material under vacuum to obtain a microporous carbon of high surface area and nitrogen/sulfur-rich composition.
