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.

“…One of the possibilities to enhance the hydrogen storage capacity in graphene material is to incorporate an active site on a graphene that is to substitute carbon atom by another element. The doping elements include N and B, however doping with P and S have also been reported [33]- [44]. It has been proposed that heteroatom might be the alternate active centers for hydrogen activation and this activated hydrogen might move to the carbon surface by spill over [45].…”

The nitrogen doped graphene was synthesized by hydrothermal route utilizing 2-Chloroethylamine hydrochloride as nitrogen precursor in the presence of graphene oxide (GO). Nitrogen-doped graphene material is developed for its application in hydrogen storage at room temperature. Nitrogen doped graphene layered material shows ~1.5 wt% hydrogen storage capacity achieved at room temperature and 90 bar pressure.

“…14 Syntheses of GNSs can be broadly categorized as bottom up and top down approach. 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.…”

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.
