Ordered nitrogen doped mesoporous carbon assembled under aqueous acidic conditions and its electrochemical capacitive properties

With urea as nitrogen source, soluble phenol-urea-formaldehyde (PUF) resin is synthesized under basic conditions and then to co-assemble with block copolymer of F127 in acidic aqueous solution to fabricate nitrogen doped mesoporous carbon. Heteroatom of nitrogen is successfully and homogeneously introduced into the skeleton of the mesoporous carbon and the final doped carbon presents a higher specific capacitance (up to 225 F/g) than nitrogen-free one (169 F/g).
