An eco-friendly and simple sol-gel autocombustion method for synthesis of copper hexaferrite nanostructures: characterization and photocatalytic activity for elimination of water contaminations. Environ Sci Pollut Res Int. 2020 Oct 25;: Authors: Sanatkar F, Khoobi A, Salavati-Niasari M Abstract In this work, copper hexaferrite (CuFe12O19) nanostructures are successfully synthesized by the sol-gel autocombustion route. Two natural reagents containing pomegranate and beetroot juices are used as green and eco-friendly fuels for synthesis of the nanostructures. The nanostructures are characterized by different techniques such as X-ray diffraction (XRD), energy-dispersive X-ray (EDX), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometry (VSM), and diffuse reflectance spectroscopy (DRS). The results show an appropriate amount of pomegranate juice as a fuel source creating a suitable route for synthesis of CuFe12O19 nanostructures. Therefore, the nanostructures are applied for degradation of different water contaminants containing eosin, erythrosine, rhodamin B, and methyl violet dyes. The comparison of the results shows that the nanostructures are a good photocatalyst for degradation of erythrosine. Therefore, green CuFe12O19 nanostructures can be a good candidate as UV light catalyst for removal of wastewater contaminatio...
