摘要
采用柠檬酸络合法制备了La1-xZnxMnO3(x为0,0.02,0.04,0.06和0.08)复合化合物,并利用XRD,TEM和紫外–可见分光光度分析等手段对其进行了表征。通过其对活性艳红X—3B的降解情况,研究其光催化活性。结果表明:所合成复合化合物为钙钛矿型结构,平均粒径为30nm。在A位掺杂Zn2+后,使LaMnO3对染料的降解率显著提高,其中La0.94Zn0.06MnO3对染料的降解率达到89.46%。
La1-χZnχMnO3 （χ = 0, 0.02, 0.04, 0,06 and 0.08） compounds were prepared by citric acid complex method and were characterized by means of XRD, TEM and UV-vis spectrophotometry. Their photocatalytic activities were investigated by degradation of reactive brilliant red X-3B. The results show that they have perovskite-type structure and their mean particle size are 30 nm. A-site doping can notedly increase the degradation rate of LaMnO3 for dyes and the degradation rate of La0.94Zn0.06MnO3 attains to 89.46%.
