Global rice production annually reaches nearly 700 hundred million tons, and the scrap from the husk outer protection sheath layer of grain of rice accounts for about 20% of the particle weight, i.e. by about 120 million tons a yearThis can be a great source material for the production of Graphene. Due to a surplus should pod has been noted as a material in the production of high-value materials such as Silicon and porous carbon dioxide. Pod was used to produce Silicon nano-porous structures are ideal for high performance lithium battery anode."In research, we make the ability to synthesize crystalline graphite with nano size range as a method of fast, stable, cost-effective and can expand the scale, using potassium hydroxide to trigger agricultural waste such as husk ash" Hiroyuki, Muramatsu ASSOC Faculty of engineering Shinshu University, Japan and also the person in charge of the work said. Join the research group also Yoong Ahm Kim, Associate Professor of science and polymeric materials University of Chonnam National.Although the production of activated carbon from the pod had a tradition for a long time, but this is the first time the structure of Graphene are observed in activated carbon produced from the pod. Researchers have realized the appearance the structure of crystalline high density ledges and uniformity of atoms in the material, though the form of Graphene are obtained in low temperature environments (850oC). Graphene nano-size crystal expresses the structure of single or multi layer with solid edge, while the fold-graphite (Graphene corrugated) includes a few nanometer size domain (200,300 carbon atoms) shows the clear grain boundary.
