Chemists at UC Berkeley have developed a covalent organic framework (COF) that can quickly suck up carbon dioxide from ambient air. This material could help get the world to negative emissions. “Trapping CO2 from air is a very challenging problem. It’s energetically demanding, you need a material that has high carbon dioxide capacity, that’s highly selective, that’s water stable, oxidatively stable, recyclable. It needs to have a low regeneration temperature and needs to be scalable. It’s a tall order for a material,” said chemistry professor Omar Yaghi. Yaghi and his team have spent the last 20 years developing these kinds of COFs. “This COF has a strong chemically and thermally stable backbone, it requires less energy, and we have shown it can withstand 100 cycles with no loss of capacity. No other material has been shown to perform like that,” Yaghi said. “It’s basically the best material out there for direct air capture.” 🔗 For more #ResearchWithResults, visit the link in our ...
