Abstract :

In this study, the advanced Hummers method )AGO( and Hummers method )HGO( were investigated, and synthesized grapheme oxides were analyzed by XRD, BET, NH3-TPD, and FTIR techniques. Analysis results showed that in the advanced Hummers method surface of carbon layers was oxidized more than Hummers method, and had more oxygenated functional groups. Experimental results indicated that synthesized graphene oxides with AGO process had less carbon layers. Also, in the absence of sodium nitrite, which is one of the main oxidants of Hummers method, production of toxic gases were eliminated in advanced method. Moreover, synthesized structures were investigated as catalyst supports in Naphtha hydro desulphurization reaction. In this venue, the synthesized compounds were impregnated by cobalt and molybdenum active phases. Moreover, the total metal loading and Co/Mo weight ratio of prepared compounds were adjusted to their industrial nominal values of 10% and 1/4, respectively
