Abstract
The Y2O3 decorated with ZnFe2O4 was successfully synthesized using Citrus limon (L.) Osbeck leaf extract for the first time. A modification of Y2O3 with ZnFe2O4 nanoparticles was carried out because Y2O3 is stable but has a wide band gap, making it less active in visible light. On the other hand, ZnFe2O4 has a small band gap and is cheap. The synthesized ZnFe2O4/Y2O3 nanocomposites, ZnFe2O4, and Y2O3 nanoparticles were characterized using FTIR, XRD, TEM, SEM, and DRS UV–Vis. TEM and DRS UV–Vis results show that the ZnFe2O4/Y2O3 nanocomposite particle has a size of 49,61 nm with a unique shape and an optical band gap of 2.08 eV. The photocatalytic activity of Y2O3, ZnFe2O4, and ZnFe2O4/Y2O3 was observed based on the photodegradation of malachite green (MG) dye under visible light. The results demonstrate that ZnFe2O4/Y2O3 can degrade MG with a photodegradation percentage of 95 % within 120 min, which is better than pure ZnFe2O4 and Y2O3. After the fourth cycle, the photodegradation percentage of MG by ZnFe2O4/Y2O3 remained at 88 %, demonstrating good reusability of ZnFe2O4/Y2O3 for photocatalytic degradation. These findings demonstrate that the use of ZnFe2O4 as a modifier may increase the photocatalytic performance of Y2O3.
