【摘要】：以乙酸鋅[Zn(CH_3COO)_2·2H_2O]、硝酸鈰[Ce(NO_3)_3]為原料,脫脂棉為模板,采用浸漬-熱轉(zhuǎn)化法制備出一系列鈰(Ce)摻雜量不同的氧化鋅(ZnO)復(fù)合中空材料,利用SEM、TG、XRD對Ce/ZnO進(jìn)行表征。借助羅丹明B的脫色降解作為模板反應(yīng),考察煅燒溫度和Ce摻雜量對Ce/ZnO光催化性能的影響。結(jié)果表明:700℃煅燒3h制得的Ce摻雜量為1%的Ce/ZnO復(fù)合中空材料對羅丹明B的降解效果最佳,紫外燈照射2h可使羅丹明B溶液的降解率達(dá)到100%。
[Abstract]:Using zinc acetate [Zn(CH_3COO)_2 2H_2O], cerium nitrate [Ce(NO_3)_3] as raw material and degreased cotton as template, a series of cerium cerium doped ZnO composite hollow materials with different doping amount were prepared by impregnation and thermal transformation method. The Ce/ZnO was characterized by Ce/ZnO.The effects of calcination temperature and ce doping on the photocatalytic properties of Ce/ZnO were investigated by decolorization and degradation of Rhodamine B as template reaction.The results showed that the best degradation effect of Rhodamine B was obtained with 1% ce doped Ce/ZnO composite hollow material calcined at 700 鈩，
