Electrochemical CO₂ Capture by a Quinone-Based Covalent Organic Framework.

ABSTRACT: Electrochemical CO₂ capture is an emerging technology that promises to be more energy-efficient than traditional thermal or pressure-swing processes. Herein, the first evidence of electrochemical capture of CO₂ using a covalent organic framework (COF) is presented. We hypothesized that the assembly of anthraquinone units into a well-defined porous framework electrode would lead to enhanced electrochemical CO₂ capture compared to previous approaches that grafted anthraquinones on carbon supports and suffered from low CO₂ capacities and stabilities. To test this, an anthraquinone-based COF is employed, and it is found that the quinones are electrochemically accessible for reversible CO₂ capture in an ionic liquid electrolyte. The system
