CaO-coated aluminosilicate foam, Cs0.9Al0.9Si2.1O6, was fabricated by utilizing a polyurethane foam, and CO2 absorption behavior of the foam was investigated. Aluminosilicate foam was fabricated by two-step heat treatment at 873 K for 20 h and 1523 K for 5 h following the coating of aluminosilicate slurry on the polyurethane foam. CaO-coated foam was fabricated by the decomposition of Ca(OH)2 pillar crystals prepared by coating CaO slurry on the aluminosilicate foam at 1073 K for 5 h, which resulted in the formation of porous CaO on the foam. The CaO-coated foam showed good CO2 absorption ability and a long lifetime for the cyclic process of CO2 absorption and desorption. The CaO-coated foam continued to maintain a CO2 absorption ratio of approximately 90% for 15 CO2 absorption and desorption cycles.
