Scientists have identified an improved approach for removing major greenhouse gas such as carbon dioxide that causes global warming from the air containing moisture and smokestacks. The report of this new process in achieving increased CO2 removal capacity from the atmosphere is published in the Journal of the American Chemical Society.
Chemistry Nobel Laureate George A.Olah, G.K Surya Prakash, Alain Goeppert and colleagues have illustrated that in the 21st century, humans have been facing critical challenges for regulating greenhouse gas emission in the atmosphere. They stated that the existing approaches for CO2 removal from the atmosphere and smokestacks are not working well. They are energy intensive and present many obstacles. Now, the scientists have started focusing on readily existing, cost-effective polyethylenimine-based solid materials to surpass these difficulties and obstacles in greenhouse gas removal methods. Some of the high grade CO2 removal rates for humid air were demonstrated in their tests using cost-effective solid materials.
The solid materials capture the CO2 gas and give it up easily so that it is permanently separated from the environment or can be used for developing other materials. The captured materials could be recycled and reused several times without reducing its efficiency.
The scientists suggest that such solid polymeric materials can be used in submarines, open atmosphere or in smokestacks to remove CO2 that is released from home heaters or cars.
