Investigation of the effect of precursor ratios on the solution combustion synthesis of zinc zirconate nanocomposite

Abstract

Zinc zirconate nanocomposite was synthesized by a low-temperature solution combustion method using citric acid as fuel at a pH of 7. The synthesis was done by varying the ratios of zirconium butoxide and zinc nitrate, which were the precursors in this study. The samples were calcined at 600 C for 2 h then their structural and optical characteristics investigated. The analysis showed that the nanocomposite consisted of mixed phases of zinc zirconate, zinc oxide, and zirconium oxide. As the Zn 2þ /Zr 4þ ratio increased, the highly agglomerated morphologies gradually developed crystalline aggregates mixed with nanorods. A red-shifted blue emission with a peak at 409 nm was observed in the photoluminescence spectra and the composites had an energy bandgap between 2.81 and 3.12 eV.

ZrO2/ZnO/TiO2 Nanocomposite Coatings on Stainless Steel for Improved Corrosion Resistance, Biocompatibility, and Antimicrobial Activity

“…In the previous study, the porosity of zinc zirconate (ZnZrO 3 ) nanoparticles containing low concentration of zinc is quite low with a crack-free sponge surface. 16 It was also reported that the zinc titanate (ZnTiO 3 ) nanomaterials exhibited much higher photocatalytic property than neat TiO 2 nanomaterials due to enhanced electron−hole separation. 17 Several methods have been reported for nanocomposite coatings such as sol−gel and plasma spray, physical vapor deposition, and chemical vapor deposition.…”
