Green synthesis of Dy2Ce2O7 nanostructure using olive leaf extract and investigating its photocatalytic performance in degradation of azo dye pollutants

For the first time, green synthesis of Dy2Ce2O7 nanostructures with use of olive leaf extract was performed. The obtained Dy2Ce2O7 nanostructures were characterized with use of methods comprising TEM, DRS, XRD and FESEM. The results of this study denoted that Dy2Ce2O7 nanoparticles with pure fluorite structure can be prepared using olive leaf extract by an easy and green way. For the first time, Dy2Ce2O7 nanostructures (prepared with olive leaf extract) were employed as an effective photocatalyst in the degradation of methyl violet pollutant in aqueous solution. Findings denoted that this photocatalyst with very good stability, under similar conditions, can destruct the methyl violet pollutant in aqueous solution during the repeated tests.
