In a new study published in the International Journal of Hydrogen Energy, scientists have developed a method of creating nanosheets of graphene from the shoots of palms.
The name is a portmanteau of graphite and the suffix -ene which represents the fact that the graphite carbon alotrope contains stacked graphite layers. The name graphhene is a single atomic layer organized in two scale grid.
Each atom in a graph sheet is bound with its nearest three neighbours, adding one electron to the conduction band spread across the whole sheet. This kind of bonding is the same as that seen in carbon nanotubes and polycyclic aromatic hydrocarbons and glassy carbon material.
The research demonstrates a simple, large-scale and cheap method for the production of a special kind of 3D graphene nanosheets from young palm shoots and NaHCO3 biomasse carbohydration.
For decades, physicists have been theorizing graphene. It was actually created unknowingly for centuries in limited numbers by the use of pencils and related graphite applications. Originally in electron microscopes in 1962, it was only examined on metal surfaces. In 2004, Andre Geim and Konstantin Novoselov at the University of Manchester discovered the substance, isolated the material and distinguished the material, which they awarded the Nobel Prize in Physics for their research into it in 2010. Amazingly easy to separate high-quality graphene and graphene dispersion in water has been accomplished for conductive and bio-interfaces patterns.
Commercialized supercapacitors have poor specific power due to their low electrical conducting and a wide variety of micro pores. Meanwhile, 3D nanomaterials have been instrumental in increasing electrochemical efficiency.
Palm shoots were "carbonized" at 350 °C. Afterwards their microstructure was verified with electron microscopy to ensure that the formed structure was suitable What they found was a peculiar multilayer structure. Novel and largely versatile 3D porous graph like nanosheets could be obtained readily provided the researchers could de-laminate and prevent the agglomeration of graphene layers.
In the various industries where 3D graphene and its derivatives are used, (sensors, fuel cells, batteries, hydrogen production and storage, solar cells and superapacitors), A 3D graph nanosheet will also be a better substitute for 2D graphen nanosheets, according to the researchers. The ability of the structure to improve charges with high energy and power densities, is of significant importance not only in academia but the production of commercial products.
