This is truly fantastic!
IIT Bombay scientists have developed a process to produce reduced graphene oxide—a wonder material with vast industrial applications—using bacteria. This bio-method for producing reduced graphene oxide is easy, low cost and green because it avoids the use of hazardous, carcinogenic chemicals and expensive laboratory instruments.
Here is some background, first. Graphene is a single, 2-dimentional layer of carbon atoms. It is produced by exfoliation of graphite, a mineral. But what you get is graphene oxide, which is a good material, but is electrically less conductive. Graphene oxide has ‘defects’, and contains 30-35 per cent Oxygen, by weight.
Reduced Graphene oxide can be obtained by removing a large percentage of oxygen content from Graphene oxide. This material contains around 5 per cent Oxygen by weight. Reduced Graphene oxide has some advantages over Graphene— can be stored longer without agglomeration and is more stable in organic solvents. Also, is more conductive.
The industry is going to need huge volumes of and and whoever gets in first has a over the others. Mass production of graphene in a cost-effective manner has been a challenge.
But now, IIT Bombay has come up with a solution.
