Abstract

See full text

A porous adsorbent structure that is capable of a reversible adsorption and desorption cycle for capturing CO2 from a gas mixture comprises a support matrix formed by a web of surface modified cellulose nanofibers. The support matrix has a porosity of at least 20%. The surface modified cellulose nanofibers consist of cellulose nanofibers having a diameter of about 4 nm to about 1000 nm and a length of about 1 µm or more that are covered with a coupling agent being covalently bound to the surface thereof. The coupling agent comprises at least one monoalkyldialkoxyaminosilane.
