Covalent Grafting of N-Containing Compound with Graphene Oxide: Efficient Electrode Material for Supercapacitor

Insight into the Fabrication and Characterization of Novel Heterojunctions of Fe2O3 and V2O5 with TiO2 and Graphene Oxide for Enhanced Photocatalytic Hydrogen Evolution: A Comparison Study

“…The deconvoluted spectrum of O 1s contains two peaks at 528.32 and 530.28 eV for g-VTMO and 528.59 and 529.74 eV for g-FTMO; these binding energies correspond to M−O (where M = Fe or V) and ketonic oxygen, respectively. 84,85,87 These results manifested the existence of Fe−O−C, V−O−C, and Ti−O−C bonds in the catalytic surface. This is evident from the slight shift in the binding energies of Fe 3+ and V 5+ from their original values.…”

“…The characteristic peaks for the C 1s spectra were located at 284.54 eV for C−C (sp 2 carbon), 286.14 eV for carboxyl carbon, and 288.43 eV for carbonyl carbon.84−86 These results confirm the existence of GO over the catalytic surface.

2D Covalent Interaction of Aminophenol Functionalized Graphene Oxide

“…The most common chemical functionalization is attachment of amino groups in to epoxy group on the surface of graphene oxide to improve the electrical, thermal and mechanical properties of composite materials(9) (10) (11) (12). The intercalation of amino group in to graphene oxide has been done by the ring opening nucleophilic substitution reaction by the -NH2 moiety attacking the epoxy group (13) (14). The acylation technique is used for the amino functionalization (15), in which the use of toxic chemicals like thionyl chloride or acyl chloride which leads to the pollution with higher toxicity.…”
