New Strategy To Enhance CO_2 Capture over a Nanoporous Polyethylenimine Sorbent

摘要

The rapidly increasing atmospheric CO_2 concentration in the past several decades is widely implicated as a major contributor to global climate change. CO_2 emissions from the combustion of fossil fuels and various chemical processes are expected to continue in the foreseeable future. To overcome the challenge in mitigating CO_2 emissions while meeting the increasing energy demand, CO_2 capture, utilization, and sequestration (CCUS) has been deemed as an important option. Therefore, capture of CO_2 in an energy- and cost-efficient manner from flue gas has attracted great attention worldwide.
