摘要：

Nanostructured Nd2Sn2O7 as highly efficient visible light driven photocatalyst has been synthesized through a new, low-temperature and facile route utilizing pomegranate juice. It is first effort to exploit pomegranate juice as novel and renewable fuel as well as green capping agent to produce the nano structured Nd2Sn2O7. The as-fabricated nanostructured Nd2Sn2O7 has been characterized with the aid of TEM, DR-UV-vis, XRD, EDS and FESEM. The findings demonstrated that optimization of preparation temperature as key factor could be advantageous and effective for control over shape, purity and grain size of Nd2Sn2O7. The photocatalytic efficiency of the nanostructured Nd2Sn2O7 produced with pomegranate juice at 500 degrees C has been examined through degrading eosin Y, eriochrome black T and methyl violet pollutants under visible illumination.
