Formation of Nanocrystalline ZnO-TiO₂ Hybrid Oxides through Hydrothermal Route

Abstract:

In this study, nanocrystalline ZnO-TiO2 hybrid metal oxide was successfully synthesized using a low-temperature hydrothermal method at 90 °C for 24 hours. Zinc nitrate hexahydrate, titanium (IV) oxide, and sodium hydroxide were employed as reactants without any additives. The synthesized ZnO-TiO2 hybrid nanomaterial was characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Field emission scanningelectron microscopy (FE-SEM), and Energy dispersive X-ray spectroscopy (EDAX). XRD results confirmed the presence of hexagonal zincite (ZnO) and rutile (TiO2) phases, with crystallite sizes of 60.28 nm and 48.12 nm, respectively. FT-IR analysis identified metal-oxide stretching vibrations, while FESEM revealed a granular and rod-like morphology, consistent with XRD results. EDAX confirmed the elemental purity of the hybrid metaloxide, detecting only Zn, Ti, and O elements. Due to its high crystallinity and controlled morphology, the ZnO-TiO2 hybrid nanomaterial has potential applications in gas sensing, environmental remediation, and energy-related fields.
