Preparation and Characterizations of Nano-Hybrid TiO₂/ZnO

Abstract:

This paper will present on preparation and characterizations of hybrid nanoTiO₂/ZnO using sol-gel spin coating techniques. The study involved of modification band-gap energy of Titanium Dioxide (TiO₂) at different precursor molecular concentration of Zinc oxide (ZnO). The FESEM (Field emission scanning electron microscope) morphological characterize shows TiO₂ and ZnO particle produced at nanoscale size. The compositional of both particles confirmed using EDAX (Energy Disperse Analyzer X-ray) analysis. The XRD (X-Ray diffraction) characterize measured the structural properties of anatase and rutile for TiO₂ as well as zincite for ZnO. By increasing ZnO molecular concentration, the crystallite size, d were decreased until the optimum sample, ratio of 4 TiO₂ : 1 ZnO, with value of 23.71 nm. For UV-VIS (Ultra-Violet/Visible Spectroscopy) measurement, we found the optical band-gap increased with increasing ZnO molecular concentration. The optical band-gap for optimum sample was 3.38 e.V represented this study has successfully improved the optical band-gap of TiO₂.
