The best way to synthesize graphene is by the process of chemical method. The Mechanical exfoliation method is possibly the technique to attain single and few layered graphene products from natural graphite by recurrent peeling/exfoliation. Chemical vapor deposition method has procedures for making thin continuous films with thickness control in micro-electronics. Plasma Enhanced Chemical Vapor Deposition (PECVD) synthesize larger part of graphene on copper foils using spin coated PMMA films. Graphene heterostructures are synthesized on cobalt substrates by means of the molecular beam epitaxial growth.

Graphene enhanced lithium ion batteries could be more beneficial for advanced energy usage applications such as in smartphones, laptops and tablet PCs. Graphene is cost-effective, flexible and extremely efficient for photovoltaics devices due to its outstanding electron-transport properties and carrier mobility. Single or few layered graphene with less agglomeration, shows higher surface area and improved supercapacitor. In hydrogen storage, hydrogen plays an important role in energy carriers. As a fuel it is light weight, comprises high energy density and produces no-harmful chemical by-products, hydrogen considered as a green energy.

Graphene based composites is currently popularized on an enormous scale. These graphene-based composites are increasing constantly, and they are available in market for their use as tennis rackets, to bikes, to skis. The execution of such materials is not almost identical to that of immaculate graphene sheets, that are measured at the nanoscale, which excellently go around settled materials, for example, steel, silicon, or copper. A significant description behind this discrepancy in properties is that it is not yet entirely seen how two-dimensional (2D) - based composites work at the nanoscale level (mechanical, electrical, and so on.) when they are fused into a mass material.

Graphene has been extensively exploited as a part of numerous applications in the current decade because of its excellent properties, that include extensive surface-to-volume proportion, exciting optical properties, outstanding electrical conductivity, high bearer portability, high transporter thickness, high warm conductivity, room temperature Hall impact, ambipolar field-impact attributes, high flag to-clamor proportion, and importantly high mechanical quality. It is a two-dimensional (2D) planar sheet of sp2-fortified carbon molecules stuffed thickly in a honeycomb like cross section. The huge scale engineering of graphene is by the help of Concoction Vapor Affidavit (CVD). A few substance alterations, biomolecular immobilization and Nano composite arrangement techniques have also been formed.

Graphenated CarbonNanotubes are new hybrid that combines graphitic foliates grown with sidewalls of bamboo style CNTs. It has high surface are with 3D framework of CNTs coupled with high edge density of graphene. Chemical modification of carbon nanotubes are covalent and non-covalent modifications due to their hydrophobic nature and improve adhesion to a bulk polymer through chemical attachment. Applications of the carbon nanotubes are composite fibre, cranks, baseball bats, Microscope probes, tissue engineering, energy storage, super capacitor etc. Nanotubes are categorized as single-walled and multi-walled nanotubes with related structures.

By alloying multiple compounds, some semiconductor materials are tunable that results in ternary, quaternary compositions. Applications of semiconductors materials are optoelectronic, solar cells, Nano photonics, and quantum optics. Fabrication of cellulose Nano-structures via Nano Synthesis is a direct conversion of TMSC layers into cellulose via a Nano-sized focused electron beam as used in scanning electron microscopes.

The initial two-dimensional (2D) material that was revealed is graphene during the year 2004. 2D Materials which are referred to as single layer materials, are the crystalline materials that involves only single layer of atoms. Since the isolation of graphene, a huge research was carried out in segregating other 2D materials owing to their distinct features and their wide applications in photovoltaics, semiconductors, electrodes and water purification. Research on these materials has increased more hastily than that of graphene since 2010.The global marketplace for 2D materials is predictable to reach USD390 million within an era, generally for graphene in their applications as semiconductor materials, electronics, batteries and composites markets. 

Graphene based Nanomaterials have abundant promising applications in vitality associated zones. Graphene enhances both energy limit and charge rate in rechargeable batteries; Enacted graphene makes dominant super capacitors for energy stockpiling. Graphene terminals is going to be the prominent methodology for creating sunlight-based cells that are economical, lightweight and adaptable. Likewise, the multifunctional graphene mats are promising substrates for synergist frameworks. The prominent energy associated areas where graphene will have an effect in sun powered solar cells, supercapacitors, lithium-particle batteries, and catalysis for energy units.

Carbon are one among those materials that can stick itself to its shape to a greater degree solid two-dimensional (2D) sheets. In this three-dimensional world, these sheets can be rolled and collapsed into several three-dimensional structures. The ball-formed fullerenes and the tube-shaped nanotubes are familiar among the three-dimensional (3D) structures. Other possible structures are carbon nanocones and Swiss cheddar like nanoporous carbon.
