23 September 2016 Current Affairs: Researchers from Pune (Maharashtra) have produced high-quality carbon from sugarcane waste within minutes by using a low power microwave system.
They had used a simple, cost-effective and quick process to convert sugarcane bagasse into anode-grade porous, conducting, activated carbon material for use in Li-ion batteries.
They had carried out initial carbonisation overnight at room temperature by mixing bagasse with concentrated sulphuric acid. The acid treatment had dissolved most of the inorganic impurities present in bagasse except silica.
This helped in forming robust carbon double bond backbone structure. The solid product obtained from acid treatment was washed thoroughly and was oven-dried at 70 degree C. Later it was mixed with potassium hydroxide to form slurry.
The slurry is then heated in a microwave oven for a few minutes. The heating had led to graphitisation and pores were formed when potassium hydroxide reacts with carbon.
