A method of preparing a mesoporous Fe&#x2014;Cu&#x2014;SSZ-13 molecular sieve includes activating an aluminum source, a silicon source, an iron source and a copper source respectively; mixing the activated minerals with sodium hydroxide, water and a seed crystal at 25-90&#xb0; C., while controlling feeding amounts of respective raw materials so that molar ratios of respective materials in a synthesis system are as follows: SiO/AlO=10-100, SiO/FeO=30-3000, SiO/CuO=1-100, NaO/SiO=0.1-0.5, HO/SiO=10-50, template/SiO=0.01-0.5; adding an acid source to adjust pH of the system for first aging; and adding the acid source again to adjust the pH of the system for second aging to obtain aged gel; pouring an aged mixture into a kettle; cooling a crystallized product and filtering to remove a liquor; washing a filter cake; drying to obtain a solid; performing ion exchange; and filtering, washing and drying the solid to obtain powder; and placing the powder in a muffle furnace.
