Epoxide-functionalization of polyethyleneimine for synthesis of stable carbon dioxide adsorbent in temperature swing adsorption

Abstract

Carbon dioxide capture technologies have been implemented as a strategy to alleviate the environmental costs of CO2 emissions. Here, the authors synthesize a functionalized-polyethyleneimine/silica adsorbent for post-combustion CO2 capture that exhibits a large CO2capacity and long-term stability.
