Reversible CO capture and release under ambient conditions is crucial for energy-efficient carbon capture and storage. Here, we report the pressure swing crystallization of CO in a single-crystalline guanidinium sulfate-based clathrate salt under practical conditions of 52 kPa and 298 K, with a high CO density (0.252 g cm) and capacity (17 wt %). The captured CO is released as a pure stream through moderate means of pressure or temperature stimulation, all while the desorbed GuaSO is ready for another cycle. The clathrate is selective exclusively to CO even in the presence of common flue gas components, such as water vapor and N, owing to the specific electrostatic interaction between the CO and guanidinium cations. The mechanism unraveled through single-crystal studies is distinctively different from physisorption or chemisorption, opening up a promising venue for future carbon capture and storage technologies through rapid CO solidification using an abundant salt.
