“…Addition of H 2 occurs across the alkenes, coupled with the extrusion of nitrogen gas, large excess of NaBH 4 have been used as a reducing agent [102]. Other reducing agents used include phenyl hydrazine [103], hydroxylamine [104], glucose, [105] ascorbic acid [106], hydroquinone [107], alkaline solutions [108], and pyrrole [109]. GO was formed by the chemical reaction between organic isocyanates and the hydroxyl is shown in Fig.…”

Graphene, a two-dimensional material of sp 2 hybridization carbon atoms, has fascinated much attention in recent years owing to its extraordinary electronic, optical, magnetic, thermal, and mechanical properties as well as large specific surface area. For the tremendous application of graphene in nano-electronics, it is essential to fabricate high-quality graphene in large production. There are different methods of generating graphene. This review summarizes the exfoliation of graphene by mechanical, chemical and thermal reduction and chemical vapor deposition and mentions their advantages and disadvantages. This article also indicates recent advances in controllable synthesis of graphene, illuminates the problems, and prospects the future development in this field.

“…The spectrum of GnP can be deconvoluted into two different peaks. The peaks at 284.8 and 289.3 eV have been assigned to the C-C/C=C in the aromatic rings, and O-C=O groups, respectively [13][14][15]. However, the C-1s XPS patterns of SAMG have been deconvoluted into four different peaks.…”

We report a covalent functionalization of graphene nanoparticles (GnPs) employing 2,3,4-Tri-O-acetyl-β-D-xylopyranosyl azide followed by fabrication of an epoxy/functionalized graphene nanocomposite and an evaluation of its thermo-mechanical performance. Successful functionalization of GnP was confirmed via thermal and spectroscopic study. Raman spectroscopy indicated that the functionalization was on the edge of the graphene sheets; the basal plane was not perturbed as a result of the functionalization. The epoxy/functionalized GnP composite system exhibited an increase in flexural modulus (~18%) and glass transition temperature (~10°C) compared to an un-functionalized GnP based epoxy composite.

“…After the reduction using TDO, the intensities for all C1s peaks of the carbon-oxygen binding species, especially the peaks of C=O and C-O bonds, decreased rapidly, revealing that most of the oxygen containing functional groups were removed after the reduction; the C/O ratio increased from 1.84:1 to 5.89:1. In previous studies, the C/O ratio for graphene obtained using L-ascorbic acid as the reductant was increased from 2.0:1 to 5.7:1 38 and from 2.7:1 to 10.3:1 using hydrazine as the reductant 39 . However, the reduction with L-ascorbic acid required 48 hours while the reduction with hydrazine required 24…”

Mass production of solution-based graphene derived from the precursor graphene oxide is a challenging step toward achieving industrialization of graphene. Inspired by a classical reducing method performed in the textile and paper making industries, we report here a rapid, cost-effective and safer approach to the facile production of graphene that employs thiourea dioxide (TDO) as the green reductant. Graphene oxide was converted into high quality graphene within 30 minutes with TDO as the reductant under moderate reaction conditions. The C/O ratio of the TDO reduced graphene was ~5.9 with the yield of graphene from graphene oxide > 99%. This is better than the reduction efficiency under the identical experimental conditions by using L-ascorbic acid as the reductant which required a reaction time of about 48 hours. This simple and effective procedure should offer an alternative route to the mass production of solution-based graphene for practical applications.
