N-doped porous carbon derived from polypyrrole for CO2 capture from humid flue gases

Abstract

Anthropogenic carbon dioxide especially emitted from coal fired power plants is a major contributor to global warming. Various carbon capture materials have been developed to mitigate CO2 emissions. However, adsorbent materials that are tolerant to the humid condition of real flue gases are rare. Here we report a N-doped porous carbon derived from polypyrrole a nitrogen-rich polymer, which can be used to capture CO2 from humid flue gases. Obtained samples were analyzed by various characterizations likewise XRD, FTIR, SEM and XPS, moreover the CO2 adsorption capacities were measured at different temperatures and relative humidities. The results indicated that the porous carbon has achieved a ..
