Solid materials for CO₂ capture and storage have attracted enormous attention for gaseous separation, environmental protection, and climate governance. However, their preparation and recovery meet the problems of high energy and financial cost. Herein, a controllable CO₂ capture and storage process is accomplished in an emulsion-templated polymer foam, in which CO₂ is breathed-in under dark and breathed-out under light illumination. Such a process is likely to become a relay of natural CO₂ capture by plants that on the contrary breathe out CO₂ at night. Recyclable CO₂ capture at room temperature and release under light irradiation guarantee its convenient and cost-effective regeneration in industry. Furthermore, CO₂ mixed with CH₄ is successfully separated through this reversible breathing in and out system, which offers great promise for CO₂ enrichment and practical methane purification.

非表面活性剂高内相乳液引发的轻触发CO ₂呼吸泡沫

用于气态分离，环境保护和气候治理的用于CO ₂捕集和封存的固体材料引起了极大的关注。然而，它们的制备和回收遇到了高能耗和财务成本的问题。本文中，在乳液模板聚合物泡沫中完成了可控的CO ₂捕获和储存过程，其中在黑暗中吸入CO ₂并在光照明下吸入CO ₂。这样的过程很可能会成为植物天然CO ₂捕获的中继，相反，植物在夜间会吸出CO ₂。可回收的CO ₂在室温下捕获并在光照射下释放，确保了其在工业中方便且经济高效的再生。此外，通过这种可逆式呼入和呼出系统成功分离了与CH ₄混合的CO ₂，这为CO ₂富集和实用的甲烷净化提供了广阔的前景。
