Nanostructured Silica-Nd2Sn2O7 Hybrid Using Fibrous Nanosilica as Photocatalysts for Degradation of Metronidazole in Simulated Wastewater

Recently, the features of photocatalysts in terms of shape, controllable size and morphology have expanded with many catalysts. In this paper a new approach of fabricating active Nd2Sn2O7 photocatalysts have expanded bymodifying the catalyst support morphology. Deposition of sustainable solution phase Nd2Sn2O7 on silica protocol was expanded on complex as well as expensive atomic layer deposition method. Generally, catalytic activity reduces by enhance in solution of Nd2Sn2O7 loading on common mesoporous silica due to the loss of surface area because of blocking of pores. It is important to note that, for dendritic fibrous nanosilica (DFNS) as a support, due to its open fibrous morphology at different Nd2Sn2O7 loading, a large value of surface area can be remained intact. It enhanced the availability of active sites that enhanced the catalytic efficiency of Nd2Sn2O7/DFNS photocatalyst. In addition, its performance as a photocatalyst in the case of adsorption of metronidazole has been tested in a batch reactor. Metronidazole is known as an antibiotic commonly utilized in veterinary medicine as well as in process of human infection, and provides aquatic environments. Usual process has not had high influence on removal of metronidazole. Therefore, in the preset study, photocatalysis adsorption of metronidazole has been examined.
