| Abstract Scope |
As atmospheric CO₂ levels rise, scalable carbon capture technologies are
urgently needed. Calcium looping (CaL) offers a low-cost, high-capacity
option for CO₂ capture at high temperatures, but industrial use is limited by sorbent sintering and performance loss over cycles. Current methods to improve stability, like template-assisted synthesis, are effective but complex and hard to scale. In this work, we introduce a novel, scalable approach combining freeze casting and CaL chemistry to create robust, gas-permeable CaO-based sorbents. Freeze casting enables porous, interconnected CaO/CaCO₃ structures with enhanced diffusivity. These sorbents operate across a wide temperature range, enabling moisture-assisted CO₂ capture at room temperature and fast carbonation at high temperatures, typical of flue gas. Our method bridges the gap between direct air capture and industrial CO₂ capture, offering a tunable platform for solid sorbents with improved performance and scalability. This work advances next-generation carbon capture materials for diverse applications. |
