CuCe-Ferrite/TiO2 Nanocomposite as an Efficient Magnetically Separable Photocatalyst for Dye Pollutants Decolorization

Abstract

In this work, a magnetically separated photocatalyst with great efficiency CuCe-Ferrite/TiO2 composite was prepared and characterized by X-ray diffraction (XRD), UV–Vis spectrophotometry, Fourier transformer infra-red spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), high resolution transmission electron microscopy (HR-TEM), energy dispersive X-ray spectroscopy (EDX) and vibrating sample magnetometer (VSM). Single-phase cubic spinel was formed by calcining the prepared sample at a temperature of 550 °C, according to the results. Different concentrations of reactive red 250 (RR250) dye photodegradation was evaluated using different doses of CuCe-ferrite/ TiO2 and TiO2 NPs. Higher efficiency of RR250 photodegradation up to 100% was obtained using CuCe-ferrite/ TiO2. The photodegradation efficiency was confirmed using chemical oxygen demand (COD) test of both treated and untreated samples. The oxidation process was mostly mediated by photogenerated .O2− according to scavenger test results. The catalyst possess higher photodegradation efficiency even after regeneration for ten times.

A Review on Impacting Parameters for Photocatalytic Degradation of Organic Effluents by Ferrites and Their Nanocomposites

“…CuCe-Ferrite/TiO 2 was used for the photodegradation of the reactive red 250 dye, and the efficiency was found to be 100% using 0.32 g/100 mL of the catalyst. A shift to more wavelength was observed due to the combination of CuCe-Ferrite andTiO 2 and hence the absorption of more visible light [28].…”

“…), superoxide anion (O 2 − ), holes (h + ), and singlet oxygen (O 2 1 ), degrade contaminants adsorbed on the surface of a photocatalyst [26]. Apart from these oxidants, other solution parameters such as the pH of the solution [27], photocatalyst quantity [28], photocatalyst surface area [29], metal and non-metal ion doping [30], light exposure, irradiation time [31], and quenchers [28] also influence the photodegradation of organic pollutants.…”

Photodegradation of a Broad-Spectrum Antibiotic Azithromycin Using H2O2 under Ultraviolet Irradiation

“…Organic dyes are degraded in water by photocatalysis using different types of nanocomposites. For example, photocatalysts have been used to eliminate methylene [ 1 , 2 ], methyl orange and Eriochrome black T [ 3 ], reactive red 250 dye [ 4 ], methylene blue and methyl orange [ 5 ], rhodamine B and crystal violet [ 6 ], methyl orange and alizarin red [ 7 ], and Congo red and methylene blue [ 8 ]. Similarly, pharmaceuticals present in wastewater have been eliminated by photocatalysis.…”
