Hydrogen have attracted much scientific interest as one of perfect energy sources because it is non-polluting and renewable. At first, graphene oxide (GO) was synthesized via a modified Hummer’s method. And then, the prepared GO was reduced via polyol reduction process to develop effective defect sites for hydrogen storage applications. According to X-ray diffraction patterns, GO was fully reduced to graphene nanosheets. From X-ray photoelectron spectroscopic analysis, it confirmed that the bonding nature of GO was changed after polyol reduction. SEM and TEM images of reduced graphene oxide show that the inter-layer distance of these materials increased than that of graphite (0.34 nm). Also, Nitrogen adsorption-desorption isotherms confirmed that synthesized reduced graphene oxide could have much amount of micropore that is effective for hydrogen storage compare to GO. Therefore, the present reduced graphene oxide could be used as a new hydrogen storage material with enhanced properties.
