Reduction and N doping of graphene oxide (GO) by H and N radicals generated on a heated metal was investigated using H2 and NH3 gas. The GO reduction occurred not only with H2 gas but also with NH3 gas. The resistance of reduced GO (r-GO) produced by this process was reduced to a range between 8×103 and 2×105 Ohm at 170 °C. The resistance of r-GO treated with NH3 gas was lower than that of r-GO treated with H2 gas, indicating that the resistance changed with the mixing ratio of NH3 and H2 gas. This suggests the possibility of N doping by radical treatment.
