Carbon dioxide capture from open air using covalent organic frameworks
A polyamine-functionalized covalent organic framework, COF-999, can be used as a material for direct air capture of CO2 from open air.
COF-999 is an exceptional material for the capture of CO 2 from open air as evidenced by its cycling stability, facile uptake of CO 2(reaches half capacity in 18.8 min) and low regeneration temperature (60 °C). This research was supported by the King Abdulaziz City for Science and Technology (Center of Excellence for Nanomaterials and Clean Energy Applications), ATOCO and the Bakar Institute of Digital Materials for the Planet.
