Abstract
Provided is a metal-containing CHA-type zeolite in which a ratio of a maximum intensity of an absorption peak in a range of 3685 cm−1 or more and 3750 cm−1 or less to a maximum intensity of an absorption peak in a range of 1800 cm−1 or more and 1930 cm−1 or less is less than 1.5 in an IR spectrum. A method for producing the metal-containing CHA-type zeolite includes a metal incorporation step of mixing a metal source and a CHA-type zeolite in which a ratio of a maximum intensity of an absorption peak in a range of 3665 cm−1 or more and 3750 cm−1 or less to a maximum intensity of an absorption peak in a range of 1800 cm−1 or more and 1930 cm−1 or less is less than 1.5 in an IR spectrum.
