New material captures carbon dioxide from air more efficiently

Researchers have developed a new material that can capture carbon dioxide from the air more efficiently. This porous substance, called covalent organic framework-999, can remove 20 kilograms of CO2 using just 200 grams of the material in a year. Unlike current carbon capture methods that work best at high CO2 concentrations, this new approach effectively adsorbs CO2 from outdoor air. The material can be reused multiple times without losing effectiveness, making it a significant advancement in direct air capture technology. The team plans to enhance this technology using machine learning. Their findings are published in the journal Nature.
