A redox-active polymeric network facilitates electrified reactive-capture electrosynthesis to multi-carbon products from dilute CO₂-containing streams.

ABSTRACT: Reactive capture - the integration of CO₂ capture with electrochemical upgrade - offers the prospect of improving overall energy efficiency in captured-CO₂-to-fuels by eliminating the gas-phase CO₂ desorption step, and by further offering a CO₂-free gas product stream. Two related challenges limit the potential impact of electrified reactive capture today: its propensity to produce lower-value C₁ products (carbon products containing one carbon atom per molecule); and its failure to retain performance when fed dilute streams (e.g. ~1-10% CO₂). We posit that these could be addressed using catalysts that locally concentrate and activate in-situ generated CO₂: we integrate a redox-active polymeric network whose polyme
