The invention relates to a preparation method of a ferrous sulfide/attapulgite composite and belongs to the field of utilization of nonmetal mineral materials. The preparation method comprises the steps as follows: a certain amount of ferric nitrate, thioacetamide and attapulgite are weighed and added to deionized water for ultrasonic treatment and stirring, a mixed liquid is transferred to a reaction kettle to react at the temperature of 160-220 DEG C, water washing and alcohol washing are performed after the reaction, drying is performed, and the ferrous sulfide/attapulgite composite can beobtained. The prepared ferrous sulfide/attapulgite composite is uniform in loading and good in dispersity, experimental raw materials are easy to obtain, no complicated equipment is required, and theferrous sulfide/attapulgite composite has a good low-temperature conversion effect on nitrogen oxide under the assistance of light. 本发明涉及种硫化亚铁/凹凸棒石复合材料的制备方法，属于非金属矿物材料利用领域。其制备方法为称取定量的硝酸铁、硫代乙酰胺和凹凸棒土，分别加入到去离子水中超声并搅拌，将混合液转移到反应釜中16
