Capturing CO₂ directly from ambient air is necessary for managing carbon levels and supporting long-term climate sustainability. However, the slow adsorption and desorption kinetics of current direct air capture sorbents remain a major limitation, whereas faster kinetics allow for quicker CO₂ uptake and greater air throughput—both are essential for enhancing system efficiency. In this work, the authors present a covalent organic framework (COF) with both fast kinetics and high CO₂ uptake.
