以石榴汁为燃料和金属硝酸盐为原料，开发了一种制备Dy2Ce2O7纳米结构的有效、简便的方法。首次开发了石榴汁作为一种新的燃料，用于简单地合成各种结构的Dy2Ce2O7，在不同的生产时间和温度下，其形状、光催化效率和粒度都不同。利用透射电子显微镜、拉曼光谱、差示扫描量热仪、X射线衍射仪、场发射扫描电子显微镜和能谱分析等手段对得到的Dy2Ce2O7的纳米结构进行了研究和表征。在可见光照射下，用不同结构的Dy2Ce2O7对赤红和亚甲基蓝污染物的光催化效率进行了评价。结果表明，以石榴汁为新燃料，在450℃下反应4h，制得的Dy2Ce2O7纳米结构对赤红素和亚甲基蓝污染物具有良好的光催化性能。
An effective and simple route is developed for production of Dy2Ce2O7nanostructures by applying juice of Punica granatum as fuel and metal nitrates. Juice of Punica granatum has for the first time been exploited as a new fuel for simple synthesis of various structures of Dy2Ce2O7in terms of shape, photocatalytic efficiency and particle size at different time and temperature for production. TEM, Raman, DRS, XRD, FESEM and EDS are exploited for study and characterization the obtained nano-sized structures of Dy2Ce2O7. Photocatalytic efficiencies have been evaluated with destruction of erythrosine and methylene blue pollutants under visible illumination over the various structures of Dy2Ce2O7. Results clearly demonstrated that the nano-sized structures of Dy2Ce2O7obtained by application of juice of Punica granatum as new fuel at 450 °C for 4 h revealed excellent photocatalytic efficiency for the destruction of erythrosine and methylene blue pollutants.
