Synthesis, photocatalytic and antidiabetic properties of ZnO/PVA nanoparticles

Résumé

Abstract We prepared a series of ZnO and ZnO/PVA catalysts by sol-gel method. The wurtzite ZnO phase was confirmed by X-ray diffraction analysis (XRD). Forming spherical shaped ZnO and ZnO/PVA nanoparticles was proved by Scanning electron microscope (SEM) images. Decomposition of Methylene Blue (MB) and methyl orange (MO) by synthesized pure ZnO and ZnO/PVA nanoparticles were studied in the UV–Vis region. ZnO/5PVA was the most active in decomposition of MB, while ZnO/7PVA was the most active in decomposition of MO. By studying biological activity of pure ZnO and ZnO/PVA in diabetic rats shows that ZnO/5PVA was the most active in lowering glucose level by different percentages.
