摘要
采用低温熔盐法制备了LaFeO3光催化剂,用X射线衍射仪(XRD)和透射电子显微镜(TEM)等测试手段对材料的结构、粒径进行了分析和表征,研究了其对罗丹明B溶液的光催化降解性能.试验表明:煅烧温度对LaFeO3粉体的结晶发育等具有重要的影响;光催化降解试验数据表明低温熔盐法制备的LaFeO3粉体具有较高的催化活性.
The LaFeO3 photocatalyst is prepared by a low temperature molten salt method and characterized by XRD,TEM techniques respectively.Its catalytic effects on the rhodamine B′s photodegradation have been investigated.The results show that the calcining temperature had a significant impact on the morphology and particle size of the LaFeO3 powder.The photocatalytic degradation data indicate that the LaFeO3 powder synthesized by the low temperature molten salt method exhibits higher photocatalytic activity.
