Development of Ionic Liquids for CO2 Absorption

The increasing manmade carbon dioxide (CO2) emission to the atmosphere is expected to rise tremendously in the next 100 years, and this will impact the environment seriously in the future. Thus, a substantial focus has been brought forward on improving techniques for CO2 sequestration. Accordingl...
