| 摘 要： | 制备了ZnO/4A沸石复合物光催化剂,并且采用了X-射线衍射仪、扫描电镜等手段进行了表征。研究表明在4A沸石表面生成了纳米ZnO颗粒,形成稳定的ZnO/4A沸石复合物。在紫外光照下选用甲基橙作为研究对象,研究了ZnO/4A沸石复合物的光催化性能,结果表明:随着ZnO纳米颗粒负载量的增大,光催化活性先提高,然后有所下降。当ZnO与4A沸石的质量比为0.5时,所制备的ZnO/沸石复合物具有较好的光催化性能。

| Abstract: | ZnO/4A zeolite composite photocatalysts are prepared,which are characterized by the X-ray diffraction(XRD),scanning electron microscopy(SEM).The results show that nano-ZnO particles are synthesized on the 4A zeolite,a stable ZnO/4A zeolite composite photocatalysts are fabricated.Irradiations are performed with UV light,and methly-orange is used as object.The experimental results indicate that the photocatalytic activity of ZnO/4A zeolite composite photocatalysts first increase and then decrease.When the rat... |
