Futurology

Here's a link to actual Nature Synthesis article instead of the nothing-burger Sky News article: https://www.nature.com/articles/s44160-024-00531-7

We found that crystalline [4[2+3]+6]cage has a CO2 uptake capacity of 3.98 mmol g−1 at 1 bar and 273 K (Fig. 7b and Supplementary Fig. 30). This CO2 uptake is high compared with other porous organic crystalline materials, such as covalent organic frameworks55, at comparable temperatures and pressures, and is one of the highest CO2 uptakes reported to date for a porous organic cage (Supplementary Table 6)56,57.

Seems interesting, but still very preliminary. Would be interesting to see if this could be scaled up to compete with simpler methods like the lime/quicklime/limestone cycle.
