We developed a hydrogen arc discharge exfoliation method for the synthesis of graphene sheets (GSs) with excellent electrical conductivity and good thermal stability from graphite oxide (GO), in combination with solution-phase dispersion and centrifugation techniques. It was found that efficient exfoliation and considerable deoxygenation of GO, and defect elimination and healing of exfoliated graphite can be simultaneously achieved during the hydrogen arc discharge exfoliation process. The GSs obtained by hydrogen arc discharge exfoliation exhibit a high electrical conductivity of ϳ2 ؋ 10 3 S/cm and high thermal stability with oxidization resistance temperature of 601 °C, which are much better than those prepared by argon arc discharge exfoliation (ϳ2 ؋ 10 2 S/cm, 525 °C) and by conventional thermal exfoliation (ϳ80 S/cm, 507 °C) with the same starting GO. These results demonstrate that this hydrogen arc discharge exfoliation method is a good approach for the preparation of GSs with a good quality.

“…Graphene has an excellent electrical conductivity, as an attractive CFE emitter should be. Several groups have demonstrated that graphene does show promising CFE properties, such as a low emission threshold field and large emission current density [6][7][8][9][10][11][12]. The present article should study the CFE of graphene theoretically.…”

The field electron emission current from graphene is calculated analytically on a semiclassical model. The unique electronic energy band structure of graphene and the field penetration in the edge from which the electrons emit have been taken into account. The relation between the effective vacuum barrier height and the applied field is obtained. The calculated slope of the Fowler-Nordheim plot of the current-field characteristic is in consistent with existing experiments.

“…As a "rising star" in materials science and nanotechnology, it holds great promise for potential applications in many fields, such as nanocomposites [2], chemical sensors [3], energy storage [4], electronics [5], photonics [6], and catalysis [7]. Graphene oxide (GO), a two-dimensional nanosheet produced by the oxidation of graphene, has attracted great interest because of its unique characteristics, such as good dispersibility and facile surface functionality [8,9].…”

A novel reduced graphene oxide (rGO) decorated organic binol based receptor ((S)-1) has been designed and synthesized. The resulting nanocomposite (rGO-(S)-1) material was then utilized as a selective fluorescent chemosensor for Ag + ion in aqueous media at physiological pH. In addition, the nanocomposite showed no cross-reaction with any of the potential interfering metal ions. The reduced graphene oxideorganic nanocomposite was characterized using various spectroscopic, microscopic and analytical studies.
