| Abstract [eng] |
Many industries stand to benefit from multicomponent crystalline oxides, including improved mobile phones and laptops, electric and hybrid cars, clean energy production, gas sensors, food fermentation, ocean exploration, and even nuclear equipment. These are only a few potential applications of lithium aluminum molybdates, lithium lanthanum titanates, and bismuth vanadates. Nevertheless, the feasibility of such applications hinges on the understanding of the properties of these materials, and the synthesis behind them. In this study, the multicomponent oxides with the general formulas of MIAlMo2O8, Li3xLa2/3−xTiO3, and Bi2O3 – V2O5 have been prepared by the aqueous tartaric acid-assisted sol-gel preparation technique. The synthesized materials underwent examination through thermogravimetric and differential scanning calorimetry (TGA-DSC), X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and energy-dispersive X-ray spectroscopy (EDS) techniques. Given the limited publications on this type of synthesis used for these materials, the main aim of this Ph. D. thesis includes the application of an aqueous sol-gel preparation technique for the preparation of the homogeneous metal tartrate gel precursors, and the characterization of the different single-phase multicomponent oxides. |
