Carbon capture: Porous trap for greenhouse gas
Date: Mar 15, 2013
Author: David Bradley
Scientists at the King Abdullah University of Science and Technology (KAUST) and the University of South Florida (USF), USA, have developed a unique, efficient, cost-effective as well reusable metal-organic framework (MOF) material, for trapping and separating carbon dioxide from various gas streams. These crystalline materials could lead to clean-air and energy-saving technologies.
