Sažetak
Green synthesis is a method that uses non-toxic, biodegradable chemicals for the synthesis of nanomaterials. This study reports an eco- friendly approach for the ultrasound-assisted synthesis of zirconia nanoparticles. In the present study, for the first time, we report a suitable green procedure for the synthesis of zirconia nanoparticles using an aqueous extract of Viscum album, as a reducing and capping agent. The biosynthesized nanoparticles were characterized by UV-visible (UV-Vis) spectrophotmetry, Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). In addition, the catalytic activity of the resulting nanoparticles was evaluated by degradation of methylene blue dye. The results of the characterization of the synthesized nanoparticles indicate the successful synthesis using Viscum album extract as a reducing agent, with UV-Vis apsorption peak at 210 nm. The FTIR identified major phytochemical compounds, which could be responsible for bio-reducing potential. The PXRD peaks show a major tetragonal phase, which is confirmed by intensity peaks at 2θ = 30˚, 50˚ and 60˚. A smaller portion of the produced ZrO2 nanoparticles has a monoclinic phase. From PXRD data, the crysrallite diameter of ZnO2 was obtained using the Scherrer equation to be 30 nm. The investigation displayed the good catalytic activity of zirconia nanoparticles on the degradation of methylene blue dye. The results showed that methylene blue has been degraded after a few hours.
