Chinese researchers capture CO2 through capture-release-compression-electrolysis
In China, in a study published in Angewandte Chemie International Edition, a research team led by the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), along with Prof. WANG Guoxiong from Fudan University, achieved efficient bicarbonate-mediated integrated carbon dioxide (CO2) capture and electrolysis to CO through an ionomer-driven reaction microenvironment control strategy.
Traditional CO2 capture and conversion routes from industrial flue gas typically follow a “capture-release-compression-electrolysis” tandem pathway. The bicarbonate-mediated integrated CO2 capture-electrolysis route, as an emerging reactive carbon capture technology, couples upstream CO2 capture with subsequent electrocatalytic conversion, reducing the energy consumption associated with obtaining high-purity CO2 feedstock.
The electrolysis of bicarbonate capture liquids is a crucial step in the bicarbonate-mediated integrated CO2 capture-electrolysis route. However, this step suffers from insufficient current density (low reaction rate) and high cell voltage (low energy efficiency).
