Table 1 summarizes a survey of the synthetic approaches and resulting capacitance values of graphene-based electrodes (see also Refs. [5-7, 11, 14, 31, 76-80] for a review of synthetic approaches). Natural graphite is the most commonly used starting material, while more atypical materials such as CNTs [46] and platelet carbon nanofibers [55] have also been used. The (modified) Hummers method [81] is the most mutual method for oxidation of carbon, while the Staudenmaier [82] and Brodie [83] methods have also been applied. Reduction of the oxidized graphite oxide nanosheets is often conducted with hydrazine. 

The type of starting material can also have a large impact on both lateral size and thickness of the graphite oxide nanosheet, which in mm impacts the specific capacitance of graphene-based electrodes. For example, it has been shown that the mass specific capacitance of commercially available graphene increases with...
