In this study, yttrium doped zinc ferrite (ZnFe2−xYxO4x = 0.01–0.1) and yttrium and copper co-doped zinc ferrite (CuyZn1−yFe2−xYxO4x = 0.1 and y = 0.5) were synthesized by solution combustion method. The synthesized nanoparticles were authenticated by various techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy–energy dispersive X-ray analysis (SEM-EDAX) and UV–visible spectroscopy. The photocatalytic activity of synthesized nanoparticles was studied by performing the degradation of methylene blue (MB) under visible light. 95% of MB was degraded in 180 min using yttrium-doped zinc ferrite. 89% of MB was degraded in 30 min using copper and yttrium co-doped zinc ferrite under visible light using 10 mg of the catalyst and 50 µl of hydrogen peroxide. Photocatalytic degradation of colorless pollutant bisphenol A also carried out using the doped zinc ferrite. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

A rapid synthetic technique is investigated for magnetic nanoparticles (Co1−yCuyFe2−xCexO4 (x = 0, y = 0), (x = 0.05, y = 0), (x = 0, y = 0.5), and (x = 0.05, y = 0.5)). The structure, morphology, optical and magnetic performance of prepared nanoparticles are analyzed by powder XRD, XPS, FT-IR, SEM-EDAX, TEM, DRS, and VSM. The photocatalytic activity of the synthesized nanoparticles for the removal of the Congo red (CR) dye and bisphenol A (BPA) from aqueous solution is examined by UV–visible spectrometer. Research indicates that the co-doping of Cu2+ and Ce3+ showed marked effect on the structural, optical, magnetic, and photocatalytic properties of the CoFe2O4 nanoparticles. DRS showed that the Co0.5Cu0.5Fe1.95Ce0.05O4 nanoparticles have lower band gap energy (0.78 eV) than other synthesized compounds. High removal percentage of CR and BPA (99.09% and 99.33%) was observed within 30 min and 180 min under visible and UV–light illumination respectively using Co0.5Cu0.5Fe1.95Ce0.05O4. The corresponding photocatalytic degradation kinetics and mechanism are analyzed. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Copper and cerium co-doped cobalt ferrite nanoparticles: structural, morphological, optical, magnetic, and photocatalytic properties

In this study, bismuth doped copper aluminate (CuAl2-xBixO4 x = 0, 0.01, 0.03, 0.05 and 0.10) nanoparticles were prepared via the solution combustion method and characterized by numerous procedures like powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, diffuse reflectance spectroscopy (DRS), scanning electron microscopy equipped with energy dispersive X-ray analysis (SEM-EDAX) and vibrating sample magnetometer (VSM). UV–Vis spectra exhibit low band gap energy ranging from 1.77 to 1.88 eV for the synthesized semiconductor oxide nanoparticles. The photocatalytic activity of copper aluminate and bismuth doped copper aluminate nanoparticles was studied by performing the decomposition of organic pollutants such as Methylene blue and Rhodamine-B under UV-light and visible light. It has been noticed from the results that the highest degradation was observed for Methylene blue dye with the bismuth doped copper aluminate (CAB03) nanoparticles compared to Rhodamine B. 99.71% degradation of Methylene blue was obtained within 60 min under UV-light irradiation and 99.90% within 60 min under visible light (H2O2) with 25 mg of catalyst. © 2017 Elsevier B.V.

Structural, optical, magnetic and photocatalytic properties of bismuth doped copper aluminate nanoparticles

In this study, cobalt ferrite and bismuth substituted cobalt ferrite (CoFe2−xBixO4 x=0, 0.1) nanoparticles were synthesized by two different methods viz combustion and co-precipitation. The nanoparticles were characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), diffuse reflectance spectroscopy (DRS), scanning electron microscopy-energy dispersive X-ray analyzer (SEM-EDX) and vibrating sample magnetometer (VSM). The results of powder XRD pattern showed an increase in lattice parameter and decrease in particle size of cobalt ferrite by the substitution of bismuth. Catalytic activity of cobalt ferrite and bismuth substituted cobalt ferrite nanoparticles synthesized by two different methods were compared for the reduction of 4-nitrophenol to 4-aminophenol using NaBH4 as a reducing agent. © 2016 Elsevier B.V.
