Performance evaluation of highly conductive graphene (RGO_HI–AcOH) and graphene/metal nanoparticle composites (RGO/Ni) coated on carbon cloth for supercapacitor applications

Abstract

The application of graphene (RGO)-based composites as electrode materials in supercapacitors can be limited by the fabrication complexity and costs, and the non-environmentally friendly nature of the production process.

Graphene Oxide Synthesis, Properties and Characterization Techniques: A Comprehensive Review

“…However, complete elimination of hydroxyl and epoxide groups is achievable even at 100 • C in vacuum. The most conductive rGO has been prepared through photoreduction, while, among the chemical reduction methods, rGO prepared with HI/AcOH exhibits the best electrical properties [79,80]. The most conductive tpGO has been synthesized by Yang et al and Wang et al [81,82].…”

Supercapacitor behavior of carbon‐manganese oxides nanocomposites synthesized by carbon arc

“…58, 59 The peak at 280.9 to 281 eV is ascribed to π-π* shake-up satellite. 60 The peak at 292.5 is attributed to the CO 2 adsorbed molecules. 61 The description of components in the O1s XPS spectra of samples is difficult due to a large amount of oxygen species in other oxides and their influences on each other.…”

“…Components at 285.5 and 286.5 eV correspond to the carbonyl and carboxyl groups, respectively 58,59 . The peak at 280.9 to 281 eV is ascribed to π‐π* shake‐up satellite 60 . The peak at 292.5 is attributed to the CO 2 adsorbed molecules 61 .…”

Graphene oxide-Cu(II) composite electrode for non-enzymatic determination of hydrogen peroxide

“…Literature shows that chemical functionalization of organic molecules or intercalation of metal species prevents the restacking of these layers [18,[24][25][26] and enhances the conductivity of GO/rGO, which has been widely used for the electrochemical applications such as sensors and energy related materials [27][28][29][30][31][32][33][34]. Recently, copper oxide/copper sulphide-graphene based composites are reported for the non-enzymatic detection of H 2 O 2 , but these methods require energy and time to synthesize the materials [2,10,14,35].…”
