Abstract
A GIS-type zeolite having an aluminum atom content of 1% by mass or more and a phosphorus atom content of 4% by mass or less, wherein a, being an amount of saturation adsorption of carbon dioxide into the GIS-type zeolite, measured when the GIS-type zeolite and carbon dioxide are placed in a system at 25° C. and 760 mmHg, is 5 cm3/g or more at 25° C. and 760 mmHg.
Claims6
A GIS-type zeolite having an aluminum atom content of 1% by mass or more and a phosphorus atom content of 4% by mass or less, wherein
