CaO-coated aluminosilicate foam, Cs_<0.9>Al_<0.9>Si_<2.1>O_6, was fabricated by utilizing a polyurethane foam, and CO_2 absorption behavior of the foam was investigated. Aluminosilicate foam was fabricated by two-step heat treatment at 873K for 20h and 1523K 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 1073K for 5h, which resulted in the formation of porous CaO on the foam. The CaO-coated foam showed good CO_2 absorption ability and a long lifetime for the cyclic process of CO_2 absorption and desorption. The CaO-coated foam continued to maintain a CO_2 absorption ratio of approximately 90% for 15 CO_2 absorption and desorption cycles.
