Reduced graphite oxide

Furthermore, some pseudocapacitors and hybrid ESs also used mixture electrolytes containing imidazolium-based ILs and organic solvents [678,694,695]. Zhang et al. [678] found the specific capacitance of asymmetric AC//Mn02 ES was increased and the internal resistance was decreased after the addition of DMF into the [BMIM][PF6] IL electrolyte, due to the improved ion mobility and penetration of the electrolyte compared with the pure IL. The optimal volume ratio of [BMIM][PF6] and DMF was 1 1, and further increasing the DMF concentration would decrease the performance. For intercalation-type carbon materials (e.g., partially reduced graphite oxide), the dilution of [EMIM][BF4] with ACN was found to increase the specific capacitance from below 100 F g up to approximately 180 F g. ...

Zheng et al. have reported the preparation of a nanocomposite consisting of PANI, RGO and palladium nanoparticles (PdNPs) [82]. First, aniline was electropolymerized by CV in a solution containing different amounts of the aniline-reduced graphite oxide complex. The PdNPs were then deposited on the composite film surface electrochemically. It was shown that by using the PANI-RGO-PdNP composite film it is possible to distinguish between the oxidation and reduction peaks of HQ and CT voltammetrically. 

Composites of PANI-PSS and carboxylated reduced graphite oxide have been used for the detection of H2O2 [83], The PANI-PSS was electropolymerized by CV on a drop cast reduced carboxylated graphite oxide layer from an aqueous solution of aniline, PSS and H2SO4. The sensor had a linear response for H2O2 between 25-350 [tM with a LOD of 1.0 x 10 M and showed no interferences for DA, AA and UA. 

Wu et al. reported a polypyrrole-reduced graphite oxide core-shell composite fabricated through electrostatic interactions, and achieved a capacity of 557 F/g at a current density of 0.5 A/g, with 85% retention of capacity after 1000 charge-discharge processes [43]. 

The art of filler dispersion in polymer matrix is easily determined by X-ray analysis especially WAXS analysis. The intensity and position of X-ray diffraction peaks reveals the exact idea regarding the morphological structure of polymer nanocomposites. Figure 22.11 compares reduced graphite oxide dispersions in NR matrix by different processes such as milling and solution casting methods.

Spin-coated or spray-deposited or filtered and subsequently reduced back to defect-decorated graphene (actually called reduced graphite oxide, RGO), either chemically (e.g., using hydrazine hydrate [63]) or thermally [64], Note that RGO is an ideal material since there is no need for a high crystalline quality graphene...

GO powder was added to a flask containing purified water (3 mg mL ). Immediately after addition, hydrazine monohydrate (1 pL for 3 mg of GO) was added to the mixture and the flask was immersed into an oil bath at 80 °C. After additional stirring for 12 h, the resulting black powder was filtered and dried to get chemically reduced graphite oxide (RGO).
