Readily regenerable amine-free CO sorbent based on a solid-supported carboxylate ionic liquid.

Accumulation of anthropogenic CO is undoubtedly the major cause of global warming. In addition to reducing emissions, minimising the threatening effects of climate change in the near future might also require the capture of enormous amounts of CO from point sources or from the atmosphere. In this regard, the development of novel affordable and energetically attainable capture technologies is greatly needed.
