SnO_2/NaY光催化剂的制备

Preparation of SnO_2/NaY photocatalyst

用二氯化锡和NaY沸石为原料，经浸渍、焙烧等工序制备SnO2／NaY光催化剂，通过X射线粉末衍射、透射电镜和紫外可见漫反射光谱表征显示：尺寸在20-60二氧化锡纳米棒在NaY沸石表面上形成；以紫外光为光源，对甲基橙溶液进行光催化降解以检验其光催化性能，结果表明：该催化剂具有紫外光催化活性。

SnO2 nanoparticles were prepared on NaY zeolite by impregnation of SnCl2 solution and subsequent calcination. The sample was characterized by XRD, TEM and UV-Vis-DRS. SnO2 nanorods on NaY zeolite obtained by this approach possess 20- 60 nm in size. The as-prepared catalyst was confirmed to be of good catalytic activity toward the methyl orange solution by using ultraviolet radiation as light source.
