Binary Ceo2-x/Ag4v2o7 Photocatalysts: Impressive Performances in Detoxification of Organic and Inorganic Pollutants

Abstract

Considering the sever threat of dangerous pollutants to unbalance the environment, it is necessary to develop an efficient and appropriate method to control and reduce environmental issues. We combined CeO2-x with Ag4V2O7 to fabricate binary novel CeO2-x/Ag4V2O7 photocatalysts through a facile hydrothermal route. Among the CeO2- x/Ag4V2O7 photocatalysts, the nanocomposite with 20 % of Ag4V2O7 was more effective than CeO2-x nanoparticles in detoxification of tetracycline (9.48 times), azithromycin (3.80 times), methylene blue (3.42 times), Fuchsine (3.58 times), and Cr (IV) (1.34-times) solutions under visible light. The charges segregation and transfer efficacious studies exhibited effective collaborations of CeO2-x and Ag4V2O7 nanoparticles in the successful reaching of the produced electron/hole pairs to the catalyst surface, and an s-scheme pathway was suggested for the charge segregation between CeO2-x and Ag4V2O7 nanoparticles. Moreover, the biocompatibility and reusability of the CeO2-x/Ag4V2O7 (20 %) photocatalyst were tested respectively in the growth of lentil seeds and four repeated runs.
