摘要
In order to deal with the increasingly serious environmental problems,it is important and necessary to lower the concentration of greenhouse gases,especially the CO_(2)gas.CO_(2)capture and storage are the relative suitable options for the reduction of these harmful gas concentration.Through the variation of mass ratio of KOH to bio-char,the as prepared active carbon PC-4 exhibits a higher specific surface area of 2491.57 cm^(3)·g^(−1),with the ultra-micropores of 0.5 and 1.2 nm.At 298 K/1 bar,the CO_(2)adsorption capacity of PC-4 also represents the highest value of 5.81 mmol/g.This work demonstrates that the both the pore size and the specific surface area are equally important to enhance the CO_(2)adsorption.This work provides a sustainable method to develop high efficiency waste-based adsorbents to deal with environmental issues of CO_(2)gas.
