摘　　要：利用离子交换法和沉淀法制备了Nd掺杂氧化锌/蒙脱土复合材料,采用XRD、IR对复合材料进行了表征,并对Nd掺杂氧化锌/蒙脱土复合材料进行了催化活性研究。对甲基橙模拟有机废水进行了光催化活性研究,在50mL、10 mg/L甲基橙模拟废液,复合材料投加量0.2 g紫外照射下,Nd掺杂氧化锌/蒙脱土、氧化锌/蒙复合材料光降解率均50%以上,其中Nd掺氧化锌/蒙脱土降解率为83.2%,高于未掺杂离子复合材料的催化效果。Nd-Doped ZnO/Montmorillonite Composites were Synthesized by using Ion exchange and precipitation method. Nd-Doped ZnO/Montmorillonite Composites were characterized by XRD,IR and their photocatalytic performance were studied. Methyl orange simulated wastewater photodegradation by Nd-Doped ZnO/Montmorillonite Composites was explored under ultraviolet light. 0. 2 g of a composites was mixed with 50 mL 10 mg/L Methyl orange simulated wastewater and have being photocatalytic under UV. The photodegradation rate of Nd-Doped Zn O/Montmorillonite Composites and Zn O/Montmorillonite Composites to methyl orange reached up more than 50%,Nd-Doped Zn O/Montmorillonite Composites reached up 83. 2%,higher than undoped ZnO/Montmorillonite Composites.
