采用溶胶-凝胶辅助静电纺丝法制备了Ag/LaFeO 3纳米带。利用扫描电镜和X射线衍射仪分别对样品的表面形貌、微观结构和晶体结构进行了分析。SEM结果表明，所制备的Ag/LaFeO 3纳米带中含有大量的孔隙。XRD分析表明，当Ag含量达到15wt%时，出现明显的Ag特征峰。随着Ag含量的增加，样品中Ag和LaFeO 3的特征峰增强。以罗丹明B水溶液为研究对象，研究了Ag/LaFeO 3纳米带在可见光下的光催化降解活性。结果表明，Ag/LaFeO 3纳米带的质量分数为15%时，具有较好的光催化活性。(C)© 2016 Elsevier B. V.版权所有。
Ag/LaFeO3 nanobelts were synthesized by a sol-gel assisted electrospinning method. The surface morphology, microstructure and crystal structure were investigated by scanning electron microscopy and X-ray diffraction respectively. The SEM results reveal that the obtained Ag/LaFeO3 nanobelts contain a large number of pores. The XRD analysis shows that when Ag content reaches 15 wt%, there are obvious Ag characteristic peaks. With the increase of Ag content, Ag and LaFeO3 characteristic peaks in the samples are enhanced as well. The photocatalytic activity of Ag/LaFeO3 nanobelts is investigated for the photo-degradation of Rhodamine B aqueous solution under visible light. The result demonstrates that 15 wt% Ag/LaFeO3 nanobelts exhibit excellent photocatalytic activity compared with others. (C) 2016 Elsevier B.V. All rights reserved.
