ZnO and ZnO-Y2O3 nanocomposites were studied for their photocatalytic degradation of Methylene blue dye, and ZnO-Y2O3 showed higher degradation efficiency and antibacterial and antioxidant activities.
ZnO and ZnO-Y2O3 nanocomposites (NCs) were investigated for their photocatalytic degradation of Methylene blue (MB) dye. X-ray diffraction study demonstrates that the hexagonal structure of ZnO has crystallite size compared to ZnO-Y2O3 NCs and confirms the cubic configuration of Y2O3. Scanning electron microscopy shows that the ZnO nanoparticles are spherical and ZnO-Y2O3 NCs have smaller particles with less agglomeration. The decreased recombining of excited e(-)/h(+) of ZnO-Y2O3 NCs is confirmed over fluorescence study. ZnO-Y2O3 exhibits a more significant degradation efficiency (96%) than ZnO nanoparticles (86%) in 120 min. ZnO-Y2O3 NCs have antibacterial as well as antioxidant activity.
