This report describes nitrogen doping of graphene nanowalls GNWs via in-situ doping during CVD growth. Based on the PIs experience with nitrogen doping in carbon nanotubes CNTs, N-doping of CNTs can be achieved to enhance deposition of Pt nanoparticles, which is effective for catalytic performance in fuel cells. He adopted a similar idea for CNTs and applied it for the growth of GNWs. The N-GNWs thus produced also showed potential for double-layered capacitors with much enhancement. Meanwhile, the micro-meter sized GNWs are idea for diffusion and intercalation of other atoms to produce novel transport properties such as superconductivity.
