Hydrothermal Synthesis of Hydrated Zinc Oxide Nanoparticles and its Characterization†

Hydrated zinc oxide nanoparticles were successfully prepared by hydrothermal method using zinc acetate and sodium hydroxide as the zinc and hydroxide sources along. The synthesized zinc oxide nanoparticles were characterized by XRD, FTIR and SEM in order to confirm the phase purity and morphology of the sample. Zinc oxide nanoparticles exhibit hexagonal wurtzite structure, which was revealed by the XRD analysis. The synthesized hydrated zinc oxide was used to modify glassy carbon electrode (GCE). The electrochemical property of the modified electrode (ZnO/GCE) was tested in a pH 7.4 phosphate buffer solutions (PBS) by cyclic voltammetry (CV). There is no peak observed in the voltammogram which indicated that the material can be used as an electrochemical sensor.
