摘　　要：以蒙古国天然丝光沸石为原料,筛选出400目的丝光沸石,对其进行改性处理后用作载体,制备负载型ZnO/丝光沸石光催化剂,并用X射线衍射、扫描电子显微镜等手段分析样品的晶相和形貌,用BET法测定催化剂的比表面积,用X射线荧光光谱仪测定催化剂中ZnO的含量.在紫外光和太阳光照射下,以罗丹明B光催化降解为探针反应,研究不同反应条件下催化剂的光催化降解性能.Natural mordenite（400mesh） from Mongolia was selected as a raw material for catalyst carrier.After the modification treatment,it was used as the carrier and a series of ZnO/modified mordenite photo-catalysts were prepared.The crystalline phase and morphology of the ZnO/modified mordenite catalysts were investigated by X-ray diffraction（XRD） and scanning electron microscopy（SEM）,BET surface areas of the catalysts and the content of ZnO in the catalysts were determined by N2 adsorption（BET） and X-ray fluorescence spectroscopy respectively.The photocatalytic degradation behavior of the catalysts for Rhodamine B under the irradiation with ultraviolet light and sunlight were studied.The relationship between the properties of the catalysts and their catalytic performance was correlated.
