摘要
The purpose of/problem addressed by the present invention is to provide: an Fe(II)-substituted MEL-type zeolite useful for the catalytic removal of a variety of gases; and a production method therefor. The SiO 2 /Al 2 O 3 ratio in this Fe(II)-substituted MEL-type zeolite is in the range of 10-30 inclusive. This Fe(II)-substituted MEL-type zeolite is obtained by being subjected to ionic exchange with Fe(II) ions. It is preferable that the Fe(II) loading amount be in the range of 0.001-0.4mmol/g of the Fe(II)-substituted MEL-type zeolite. It is preferable that the Fe(II)-substituted MEL-type zeolite be produced using a method in which an MEL-type zeolite having an SiO 2 /Al 2 O 3 ratio in the range of 10-30 inclusive is dispersed in an Fe(II) water-soluble-compound aqueous solution, and then mixed and agitated to cause the MEL-type zeolite to carry Fe(II) ions.
