Abstract
Effect of atomic hydrogen annealing (AHA) on graphene oxide (GO) was investigated. In AHA, the high-density atomic hydrogen is generated on heated tungsten (W) surface by catalytic cracking reaction. From X-ray photoelectron spectra, GO films were reduced by AHA. The sheet resistance of the GO film was decreased by 5 orders of magnitude at W mesh temperature of 1780 °C, sample temperature of 220 °C and treatment time of 1800 s. The reduction of GO films relates chemical reaction due to atomic hydrogen because the GO films was not reduced by He treatment. The C-O-C bonds in GO films were preferentially reduced by AHA.
