Nanofiltration approach can solve a bottleneck for CO₂ capture and conversion

Removing carbon dioxide from the atmosphere efficiently is often seen as a crucial need for combating climate change, but systems for removing carbon dioxide suffer from a tradeoff. Chemical compounds that efficiently remove CO₂ from the air do not easily release it once captured, and compounds that release CO₂ efficiently are not very efficient at capturing it. Optimizing one part of the cycle tends to make the other part worse.
