Abstract
Carbon dioxide (CO2) capture materials comprising one or more 3D-printed zeolite monoliths for the capture and or removal of CO2 from air or gases in enclosed compartments, including gases or mixtures of gases having less than about 5% CO2. Methods for preparing 3D-printed zeolite monoliths useful as CO2 capture materials and filters, as well as methods of removing CO2 from a gas or mixture of gases in an enclosed compartment using 3D-printed zeolite monoliths are provided.
Claims10
A method of preparing a 3D-printed zeolite monolith, the method comprising:
- mixing zeolite powder, bentonite clay, a plasticizing organic binder, and an organic co-binder using a high-performance dispersing instrument at 2500 rpm to obtain a powder mixture;
- adding a sufficient amount of distilled water to the powder mixture and mixing using the high-performance dispersing instrument at 2500 rpm to form an aqueous paste;
- and
- depositing the aqueous paste layer-by-layer, using a 3D-printing apparatus, onto a substrate to produce a 3D-printed zeolite monolith.
