Mitigation of anthropogenic climate change is expected to require large-scale deployment of carbon dioxide removal strategies. Prominent among these strategies is direct air capture with sequestration (DACS), which encompasses the removal and long-term storage of atmospheric CO₂ by purely engineered means. Because it does not require arable land or copious amounts of freshwater, DACS is already attractive in the context of sustainable development, but opportunities to improve its sustainability still exist. Leveraging differences in the chemistry of CO₂ and water adsorption within porous solids, here, the prospect of simultaneously removing water alongside CO₂ in direct air capture operations is investigated. In many cases, the co-adsorbed water can be desorbed separately from chemisorbed CO₂ molecules, enabling efficient harvesting of water from air. Depending upon the material employed and process conditions, the desorbed water can be of sufficiently high purity for industrial, agricultural, or potable use and can thus improve regional water security. Additionally, the recovered water can offset a portion of the costs associated with DACS. In this Perspective, molecular- and process-level insights are combined to identify routes toward realizing this nascent yet enticing concept.

同时捕获二氧化碳和从空气中收集水的前景

预计减缓人为气候变化需要大规模部署二氧化碳去除策略。这些策略中最突出的是带封存的直接空气捕获 (DACS)，它包括通过纯工程手段去除和长期储存大气中的 CO _{2 。}因为它不需要耕地或大量淡水，DACS 在可持续发展的背景下已经很有吸引力，但提高其可持续性的机会仍然存在。利用多孔固体内 CO _{2的化学性质和水吸附的差异，在这里，与 CO}₂ 同时去除水的前景在直接空气捕获操作中进行了调查。_{在许多情况下，共同吸附的水可以与化学吸附的 CO 2}分子分开解吸，从而能够有效地从空气中收集水。根据所使用的材料和工艺条件，解吸水可以具有足够高的纯度以供工业、农业或饮用水使用，因此可以提高区域水安全。此外，回收的水可以抵消与 DACS 相关的部分成本。在这个观点中，分子和过程水平的见解被结合起来，以确定实现这一新生但诱人的概念的途径。
