Preparation method for Fe-containing mesoporous mordenite with high catalytic activity

The invention discloses a preparation method for Fe-containing mesoporous mordenite with the high catalytic activity, which relates to a preparation method for the Fe-containing mesoporous mordenite. The problem of low catalytic activity of the mesoporous mordenite obtained with the traditional preparation method is solved. The preparation method comprises the following steps of: 1) crystallizing after a silicon source, an aluminum source, NaOH and deionized water are mixed, and successively preparing sodium-type, ammonium-type and hydrogen-type mordenite; 2) adding the hydrogen-type mordenite obtained in step 1) into HNO3 solution, controlling the concentration of the HNO3 solution, adding NaOH solution after heating reflux and drying, and obtaining the mordenite with the mesoporous structure; and 3) mixing with different Fe-containing ionic solutions, and calcining to obtain the Fe-containing mesoporous mordenite at high temperature after washing and drying. The Fe-containing mesoporous mordenite prepared w
