Synthesizing nanocomposite TiO2@ZnFe2O4 using a simple one-pot solvothermal technique

Abstract

Abstract This paper reports solvothermically the synthesis of TiO2@ZnFe2O4 nanocomposite. It was synthesized and characterized by several procedures with a weight ratio of 2 percent. X-ray diffraction tests were detected at 24.45° to show the typical weak peaks in TiO2@ZnFe2O4, confirming TiO2 (anatase) at 30.10°, 35.47°, 41.06°, 45.64°, 56.64° and 62.51°, which represent a characteristic peak of the ZnFe2O4 - orientations (220), (311), (400), (422), (511) and (440), respectively. The nanocomposite has been found to have significant peaks at 311° and 411°. The preparation of TiO2@ZnFe2O4 nanocomposite is confirmed by Fourier-transform infrared. FESEM was also conducted to analyze TiO2@ZnFe2O4’s shape and structure. In addition, information in line with IUPAC type III and the H2 hysteresis loops were provided by the BET isotherm and the BJH technique. In the surface, pore-volume, and pore diameter, the findings have supported effective changes. Diffuse reflection spectroscopy gave more information on the modifications that occurred in the nanocomposite to alter the spectrum to the red region while reducing the band gap to 1.65 eV. These findings have strengthened the structure of nanocomposite as-prepared.
