Development of Sn/Nio3 and Ce/Nio3 Nanocomposites and Its Application in Waste - Water Treatment

Abstract

To synthesis nickel oxide nanocomposites based on tin and cerium, a simple hydrothermal method was employed. The synthesized NiO, Sn/NiO₃, and Ce/NiO₃ nanoparticles were characterized using analytical methods as XRD, FT-IR, SEM, and UV-DRS. The crystalline sizes of NiO, Sn/NiO₃ and Ce/NiO₃ are 29.4, 36.7 and 47.6 nm, respectively. When surface morphologies were investigated using SEM, it was discovered that NiO, Sn/NiO₃ and Ce/NiO₃ nanocomposite showed spherical, agglomerated matrix and irregular structures. The Sn/NiO₃ band gap was 2.5 eV and Ce/NiO₃ was 2.0 eV, respectively, according to the Kubelka-Munk function plot, which was used to determine the band gap using UV-DRS analysis. Using methylene blue dye, we were able to achieve up to 83.2% degradation efficiency property in Ce/NiO₃ nanocomposites through photocatalytic degradation.
