中文摘要：

采用水热法合成了锌铁氧体与活化粉煤灰复合材料．X射线衍射谱图（XRD）表明复合材料的颗粒度较小，对应较大的比表面积．扫描电子显微镜（SEM）照片显示复合材料的颗粒度为50～80nm．光催化降解罗丹明B的测试表明，活化粉煤灰具有非常好的吸附性能，与锌铁氧体复合后，其光催化性能增强了50％以上．该研究结果将对半导体材料光催化降解污染物的实际应用有所帮助和启发．

英文摘要：

The activated fly-ash and zinc ferrite composites were synthesized by hydrothermal method. The X- ray diffraction showed that the grain size of the composites were small which would be beneficial to the photocatalytic performance. Scanning electron microscopy showed the grain size of the composites was 50 - 80 nm. The photocatalytic activities of the degradation of Rhodamine B under visible light using AFA, zinc ferrite, and zinc ferrite/AFA composites were investigated. The results showed that AFA hybridized with zinc ferrite had higher photocatalytic performance than zinc ferrite of 50% ,which might be useful in the future.
