“…The optical properties of the MnO 2 nanoparticles and the MnO 2 -AC nanocomposites were characterized by means of the Schuster–Kubelka–Munk (SKM) model [ 57 , 58 ] through UV–VIS absorption measurements. Both samples showed the optical absorption bands at the visible wavelength regions ( Figure 5 a).…”

In the present work, we demonstrated the upcycling technique of effective wastewater treatment via photocatalytic hydrogen production by using the nanocomposites of manganese oxide-decorated activated carbon (MnO2-AC). The nanocomposites were sonochemically synthesized in pure water by utilizing MnO2 nanoparticles and AC nanoflakes that had been prepared through green routes using the extracts of Brassica oleracea and Azadirachta indica, respectively. MnO2-AC nanocomposites were confirmed to exist in the form of nanopebbles with a high specific surface area of ~109 m2/g. When using the MnO2-AC nanocomposites as a photocatalyst for the wastewater treatment, they exhibited highly efficient hydrogen production activity. Namely, the high hydrogen production rate (395 mL/h) was achieved when splitting the synthetic sulphide effluent (S2− = 0.2 M) via the photocatalytic reaction by using MnO2-AC. The results stand for the excellent energy-conversion capability of the MnO2-AC nanocomposites, particularly, for photocatalytic splitting of hydrogen from sulphide wastewater.

“…Potassium ferrite is a good candidate for this application, as iron and potassium are biocompatible and non-toxic materials [3]. Magnesium ferrite is an n-type semiconductor material with a spinel structure [4,5]. Consequently, it has been applied in many fields as sensors, photocatalysts, and anode materials [6][7][8][9].…”

Graphene oxide (GO) nanostructures are systems with many fascinating novel properties that can be used to study new science and have significant promise for applications. In this study, graphene oxide was prepared using the modified Hummer’s method. In addition, potassium ferrite is a good candidate for biomedical application, as iron and potassium are biocompatible and non-toxic materials. Mg0.85K0.3Fe2O4/GO nanocomposites were prepared by the citrate auto-combustion method. The effect of adding GO to Mg0.85K0.3Fe2O4 on structure, morphology, electrical, and magnetic properties was discussed. Samples under investigation were characterized using XRD, infrared spectroscopy (IR), high-resolution transmission electron microscopy (HRTEM), and atomic force microscopy (AFM). The crystallite size of prepared samples was decreased from 28.098 to18.148 nm by increasing GO content. Scanning electron microscope (SEM) confirms the successful adhesion of Mg0.85K0.3Fe2O4 nanoparticles on graphene oxide sheets, which are dispersed in a metal oxide matrix. EDAX analysis confirms the existence of C, O, K, Mg, and Fe elements present in the samples. Magnetic properties were studied by VSM and Faraday's method. GO has a significant effect on the magnetic properties of nanocomposites. For instance, the saturation magnetization and Curie temperature have diverse values, which will be appropriate for numerous applications.

“…The particlesize distribution is given by the histogramas shown in Fig.3b. Fig.4displays the hysteresis loop of the investigatedsample, which designates the soft natureof the sample. The sample exhibits very low coercivity values indicating that the sample belongs to the family of soft magnetic materials [10]. The values of the saturation magnetization(Ms), coercivity (Hc), retentivity (Mr), energy loss and squareness(Mr/Ms)are obtained andtabulated in Table 1.…”
