Graphene was the first 2D material to be isolated. Graphene and other two-dimensional materials have a long list of unique properties that have made it a hot topic for intense scientific research and the development of technological applications. These also have huge potential in their own right or in combination with Graphene. The extraordinary physical properties of Graphene and other 2D materials have the potential to both enhance existing technologies and also create a range of new applications. Pure Graphene has an exceptionally wide range of mechanical, thermal and electrical properties. Graphene can also greatly improve the thermal conductivity of a material improving heat dissipation. In applications which require very high electrical conductivity Graphene can either be used by itself or as an additive to other materials. Even in very low concentrations Graphene can greatly enhance the ability of electrical charge to flow in a material. Graphene’s ability to store electrical energy at very high densities is exceptional. This attribute, added to its ability to rapidly charge and discharge, makes it suitable for energy storage applications.

Large molecular building blocks for hybrid materials, such as large inorganic clusters, may be of the nanometre length scale. The term hybrid material is more often used if the inorganic units are formed in situ by molecular precursors, for example applying sol–gel reactions. The biggest distinction between a Nano composite and a hybrid is that a hybrid material possesses a property that does not exist in either of the parent components. Graphene and single-walled carbon nanotubes are carbon materials that exhibit excellent electrical conductivities and large specific surface areas. An effective, economic way of using carbon fiber is to combine it with a resin and another material, either a fiber or a metal, to produce a hybrid structure.

Graphenated Carbon Nanotubes 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.

Carbon is an extraordinary element because of its ability to covalently bond with different orbital hybridizations. This leads to a rich variety of molecular structures that constitute the field of organic chemistry. For millennia, there were only two known substances of pure carbon atoms: graphite and diamond. The discovery of nanometre dimensional C60, and related fullerene-structures (C70, C84), spawned the field of Nano carbon research. The next major advance in carbon research was the discovery of carbon nanotubes (CNTs).The traditional electrochemical applications for carbon in solid electrode structures for the chlor-alkali industry as well in aluminium refining are giving way to more diverse applications requiring high-surface-area carbon i.e., capacitor, fuel cells, metal/air batteries and high-energy lithium batteries. In these of these applications carbon has the desirable combination of acceptable electrical conductivity, chemical/electrochemical compatibility to the surrounding environment, and availability in the appropriate structure for fabrication into electrodes. In addition, the low cost of carbon relative to other electronic conductors is an important advantage for its widespread use in electrodes, particularly in electrochemical systems that must compete with existing technologies. Diamond electrodes are particularly attractive for electrochemistry Because of its extraordinary chemical stability; diamond is a perspective electrode material to be used in electrochemistry and electrochemical engineering.

Carbon materials touch every aspect of our daily life in some way. Regarding todays environmental challenges carbon may be the key elemental component, usually blended into notations such as “carbon cycle” or “carbon footprint”. Interestingly, not being used as “fossil fuel”, carbon materials also considerably contribute to the field of sustainable energy. They are central in most electrochemical energy-related applications, i.e. they also help to generate, store, transport, and save energy. Nanostructured carbon is already used in fuel cells, conventional batteries and super capacitors. Electric double layer capacitors (EDLC, also called super capacitors) are energy storage devices based on the electrical adsorption of ions at the electrode/electrolyte interface (non-Faradaic process). Porous carbons are being used widely as electrode materials for super capacitors because of their high specific surface area and relatively good electrical conductivity.

Nano carbons are among the most promising materials developed last years. Nano carbon materials include fullerenes, carbon nanotubes (CNT), carbon nanofibers (CNF), nanodiamond, onions and various hybrid forms and 3D structures based on these. Nano carbon materials such as carbon nanotubes (CNT's) and graphene have many extraordinary properties, such as a factor of 1000 times higher mobility and 10 times larger saturation velocity than Si. Several years ago these materials were available in milligram-scale quantities. Now many of them are produced by tones per year.

Carbon nanotubes (CNTs) are cylinders of one or more layers of graphene (lattice). Diameters of single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) are typically 0.8 to 2 nm and 5 to 20 nm, respectively, although MWNT diameters can exceed 100 nm. CNT lengths range from less than 100 nm to 0.5 m. Individual CNT walls can be metallic or semiconducting depending on the orientation of the lattice with respect to the tube axis, which is called chirality. carbon nanotube production exceeded several thousand tons per year, used for applications in energy storage, automotive parts, boat hulls, sporting goods, water filters, thin-film electronics, coatings, actuators and electromagnetic shields, health care and environmental protection.

Graphene-enchaned lithium ion batteries could be used in higher energy usage applications now in smartphones, laptops and tablet PCs. Graphene has a great potential to use for low cost, flexible and highly efficient photovolatics devices due to its excellent electron-transport properties and carrier mobility. Single or few layered graphene with less agglomeration, exhibit a higher effective surface area and better supercapictor. In hydrogen storage, hydrogen plays an important role in energy carriers. As a fuel of choice it is light weight, contains high energy density and emits no-harmful chemical by-products, hydrogen considered as a green energy.
