摘要
本文分别采用溶胶-凝胶法和流变相法制备催化剂LaFeO3、LaCoO3、LaMnO3、LaN iO3和LaC rO3。用X射线衍射(XRD)和透射电子显微镜(TEM)进行了表征。以甲基橙和十二烷基苯磺酸钠的光催化降解率评价了所制备的催化剂的活性。结果表明对甲基橙的降解LaN iO3和LaCoO3有较高的活性,对十二烷基苯磺酸钠的降解LaCoO3的活性最高。
Pervoskite type oxides such as LaFeO3,LaCoO3,LaMnO3,LaNiO3 and LaCrO3 were prepared by using sol-gel and rheological phase method and characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM).The photocatalytic activities of the catalysts were investigated for photocatalytic degradation of methyl orange and DBS.The results show that the better activities are LaNiO3 and LaCoO3 for methyl orange and the best activity is LaCoO3 for DBS.
