Synthesis of CeO2/NiFe2O4 Nanocomposites and their Photocatalytic Activity of Methyl Orange Dye under UV-Visible Irradiations

Abstract

Using the hydrothermal technique CeO2/NiFe2O4 for exceptional photocatalytic activity, nanoparticles are fabricated. Methyl Orange dye according to its toxicity, color, and environmental hazards was used as aqueous pollutant source for photocatalytic experiment results. The synthesized nanoparticles were characterized by various techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), UV-visible spectroscopy, scanning electron microscopy (SEM). The photocatalytic activity of synthesized nanoparticles was studied by conducting the degradation of methyl orange under the visible light. PL spectra were verified for the recombination and separation time for the synthesized nanoparticles in different light regions. 88.57% of Methyl Orange was degraded in 120 min. The result attests to low cost, reusable and high efficiency photo catalyst for environmental remediation. The synthesize sample is easily separable using any external magnetic source. In addition, sample results show the shifting of absorption spectrum towards the visible region of light. FTIR and XRD results show the functional and cubic spinel shape photo catalysis formation. SEM images show the morphology of the sample. Reusability and stability experiment exhibit the miner reduction in catalyst efficiency percentage after five cycles. According to extraordinary applications the synthesize sample are used on large scale for Industrial Waste Water treatment process in future.
