Synthesis & Characterization of Zirconium Oxide (ZrO2) Nanoparticles in Hydrothermal
Nouraldin Almahdi Ibrahim Basha [3]
Abstract: Heavy metals are well - known environmental pollutants owing to their toxicity, longevity in the atmosphere, and ability to accumulate in the human body via bioaccumulation. The pollution of terrestrial and aquatic ecosystems with toxic heavy metals is a major environmental concern that has consequences for public health. The paper presents the preparation and investigations of zirconium oxide (ZrO2) nanoparticles that were synthesized by hydrothermal process. The ZrO2 nanoparticles were well characterized by using different sophisticated instrumentation techniques like UV - Vis, FT - IR, XRD, TEM, EDAX, and DLS. The formation of ZrO2 NPs was primarily confirmed by its characteristic absorption band at 342 nm using UV - Visible spectroscopic hydrothermal analysis. The crystal structure was determined using X - ray diffraction. The morphology and the particle size were studied using (SEM) and (TEM). The spherical shaped particles were confirmed through the SEM analysis. The transmission electron microscopic analysis confirmed the formation of the nanoparticles with the particle size. The FT - IR and Raman spectrum ascertained the strong presence of ZrO2 nanoparticles. The optical properties were obtained from UV?visible absorption spectrum and also PL emission spectrum. The Energy Dispersive X - ray spectroscopy technique was used to identify the elemental composition of the ZrO2 Nano - particles. The dielectric constant and the dielectric loss were measured as a function of frequency and temperature.
