Development of Ca(OH)2nanosorbent for intermediate-high temperature CO2 capture via wet chemical route in N,N-Dimethylformamide solvent

CO2 is the major anthropogenic greenhouse gas which contributes to the increasing atmospheric CO2 concentration, leading to serious global warming and climate change. Thus, the present paper investigates the CO2-capture performance of synthesized calcium hydroxides, Ca(OH)2nanosorbent at intermed...
