Researchers at the Institute of Advanced Materials (INAM) and the Department of Physical Chemistry at the Universitat Jaume I of Castelló, led by researcher Marcileia Zanatta, have developed a new class of absorbents for the efficient capture of carbon dioxide (CO2) directly from the air, as well as from other dilute gas streams. A Spanish patent application has been filed for this invention, and partners are being sought for the commercial exploitation of the salts and capture methods, the industrial scale-up of the process, and its validation in real operating environments.
