Abstract
Effective use of unique structural and electronic properties of UV light has made more researchers extremely involved for photocatalytical systems. The synthesis of CeO2 nanoparticle (NPs) has been successfully achieved by using Cardiospermum halicacabum L leaf Extract. The nanoparticle was characterized by High-resolution scanning electron microscopy (HR-SEM) with elementary dispersive X-ray (EDX), High-resolution transmission electron microscopy (HR-TEM), XRD analysis, FT-IR, FT-Raman, photoluminescence spectroscopy (PL) and UV–Vis DRS. This plant extract CeO2 nanopartricles has high photocatalytic activity of Rh B dye that of chemical method CeO2 nanopartricles and at various parameters was reported. Mineralization of dyes is confirmed by measurements of chemical oxygen demand. The reaction of this nanoparticle was described as a feasible mechanism. This catalyst was found to be stable and reusable. This nanoparticle has electrochemical activity showed highest activity by bio synthesis of CeO2 nanoparticle compared that of chemical synthesis CeO2 nanoparticle was reported in this article.
