Chiba University team develops viciazites for cheaper, easier CO2 capture

In Carbon, researchers reported three nitrogen-configured materials; the adjacent-NH2 version released most captured CO2 below 60C, potentially using industrial waste heat.
The team said controlled adjacent nitrogen placement improved uptake in NH2 and pyrrolic variants, while pyridinic material showed little gain; selectivity reached 76%, 82% and 60% in synthesis.
The work aims to cut costs versus amine scrubbing, which typically needs heating above 100C, and could also support metal-ion removal or catalytic applications.

What new challenges might arise if low-temperature CO2 capture becomes widespread due to materials like viciazites?

Could viciazites transform global carbon capture if their durability and scalability are proven outside the lab?
