In this work, we have prepared the activated graphite oxide (GO) by CO2 activation as a function of temperature, in order to enhance the hydrogen storage capacity. The microcrystalline structures and morphologies of samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) measurements, respectively. The hydrogen storage capacities of the samples were improved with CO2 activation temperature, resulted from the formation of exfoliated structure in the activated GO. In conclusion, we suggested that the physical activation by CO2 gas was one of the effective methods to enhance hydrogen storage capacity of graphite oxide. |
