“…Scotch tape peeling, 1 exfoliation of graphite in various solvents (or liquid phase exfoliation) 15,16 and the arc discharge technique 17 include the most practiced top down approach techniques. Whereas the epitaxial growth techniques, 18,19 thermal annealing of silicon carbide, 20 self-assembly on metallic substrate 21 solvothermal reaction, 22 gas-phase microwave-production 23 and chemical vapor deposition (CVD) on di®erent substrates [24][25][26][27] are usually adopted for bottom up fabrication of GNSs coating. A signi¯cant amount of research has been carried out by Banks et al 14,[27][28][29][30][31][32] towards CVD synthesis of graphene sheets and its applications in various functional performance based sectors.…”

We report an e±cient and green approach for mass production of few layered graphene nanosheets (FLGNSs) by intercalation and exfoliation of pyrolytic graphite sheet in a simple protic, H 2 SO 4 electrolyte. The as-prepared FLGNSs at the optimum intercalate concentration of 0.5 M H 2 SO 4 is able to produce large domain of lateral dimension of 11-26 m consisting of 4-6 stacked graphene layers, as con¯rmed by¯eld emission scanning electron microscopy and atomic force microscopy, respectively. Surface oxygenation and a characteristic absorbance peak at 228 nm are well observed for electrochemical exfoliated FLGNSs from Fourier transform infrared spectroscopy and UV-Vis spectra respectively. (002) planes of the obtained graphene sheets have been con¯rmed from X-ray di®raction pattern. The characteristic Raman bands have been observed at 1354 cm À1 and 1590 cm À1 in the exfoliated FLGNSs.

Graphene paper as a new form of graphene-supported nanomaterials has received worldwide attention since its first report in 2007. Due to their high flexibility, lightweight and good electrical conductivity, graphene papers have demonstrated the promising potential for crucial applications in electrochemical sensors and energy technologies among others. In this chapter, we present some examples to overview recent advances in the research and development of two-dimensional (2D) graphene papers as new materials for electrochemical sensors. The chapter covers the design, fabrication, functionalization and application evaluations of graphene papers. We first summarize the mainstream methods for fabrication of graphene papers/membranes, with the focus on chemical vapour deposition techniques and solution-processing assembly approaches. A large portion of this chapter is then devoted to the highlights of specific functionalization of graphene papers with polymer and nanoscale functional building blocks for electrochemical-sensing purposes. In terms of electrochemical-sensing applications, the emphasis is on enzyme-graphene and nanoparticle-graphene paper-based systems for the detection of glucose. We finally conclude this chapter with brief remarks and outlook.

Graphene-derived materials are currently studied because of their actual and projected applications. Among them, graphene oxide (GO) promises for outstanding applications as it can be prepared at large scale by simple, scalable, and low-cost techniques. The existent chemical methods based on the graphite exfoliation (phase solution and Hummers based) produce highly functionalized graphene, i.e., GO-like materials that converts into reduced GO (rGO) after a reduction treatment. The present work presents the current scenario on the GO green reduction methods, on the development of hierarchical carbon-based structures by the self-assembly of GO sheets at interfaces, and on rGObased hybrid nanocomposites. It is worth noting that, to date, the production and application of graphene-related materials are the fastest-growing research areas.
