CO2 Capturing and Mineralization by (Mg)-Phyllosilicate Coated with Fabrics.

Abstract

To promote the practicality of magnesium (Mg)-phyllosilicate as a potent carbonation agent, two inexpensive cotton and nylon fabrics are selected and examined to assess their feasibility for use as supporting media of Mg-phyllosilicate. Mg-phyllosilicate is coated onto the fabrics via a sol-gel method, whose mechanism is explained. The characteristics of the Mg-phyllosilicate coated cotton, along with those of the carbonation products, are explored. Mg-phyllosilicate is found to mediate the carbon dioxide (CO2) mineralization process actively, even on cotton of a supporting material. Conclusively, the obtained results clearly support the potential of mineralization as a feasible option for capturing CO2, in particular with the abiotic catalyst of Mg-phyllosilicate coated onto flexible cotton.
