“…Based on the previously reported literature, it can be assumed that the flake-like morphology could belong to the NiO component of the heterostructure, while the clusters could be the ZnO and Eu 2 O 3 NPs in the heterostructure. 46 Elemental mappings of bulk ZnO/Eu 2 O 3 /NiO have been collected and displayed in Figure 5. It shows that the asprepared heterostructure contains the desired elemental composition, and the elements are well dispersed throughout the composition, which can play a synergetic role in the enhancement of the catalytic performance.…”

The ZnO-based ternary heterostructure ZnO/Eu2O3/NiO nanoparticles are synthesized using waste curd as fuel by a simple one-pot combustion method. The as-synthesized heterostructure is characterized by using various spectroscopic and microscopic techniques including X-ray diffraction, UV–vis, FTIR, SEM, and TEM analyses. The photocatalytic activity of the ternary nanocomposite was tested for the photodegradation of methylene blue (MB) under solar light irradiation. The results have revealed that the ternary ZnO/Eu2O3/NiO photocatalyst exhibits excellent performance toward the photocatalytic degradation of the studied dye. Optimization studies revealed that the synthesized heterostructure exhibited a pH-dependent photocatalytic activity, and better results are obtained for specific concentrations of dye and catalysts. Among the different light sources employed during the study, the catalyst was found to possess the best degradation efficiency in visible light.

“…Graphene (G) and its family materials including graphene oxide (GO) and reduced graphene oxide (rGO) have been used widely for metal corrosion protection [1][2][3][4], which is beneficial due to its excellent physical barrier, chemical and electrochemical properties. However, because of strong van der Waals forces and high specific ratio, G, GO or rGO tend to easily aggregate each other, which greatly limits their functional development and industrial applications [5][6][7].…”

Reduced graphene oxide–epoxy grafted poly(styrene-co-acrylate) composites (GESA) were prepared by anchoring different amount of epoxy modified poly(styrene-co-acrylate) (EPSA) onto reduced graphene oxide (rGO) sheets through π–π electrostatic attraction. The GESA composites were characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The anti-corrosion properties of rGO/EPSA composites were evaluated by electro-chemical impedance spectroscopy (EIS) in hydroxyl-polyacrylate coating, and the results revealed that the corrosion rate was decreased from 3.509 × 10−1 to 1.394 × 10−6 mm/a.

“…Low magnification FE-SEM micrograph as displayed in Figure 4 a,b reveals that the Mn 3 O 4 /ZnO/Eu 2 O 3 is composed of clusters of flakes, in which all the flakes are interconnected and form a net-like structure with large pores ( Figure 4 c). According to the formerly reported studies, it can be said that the flakes could belong to the Mn 3 O 4 NPs of the material, whilst the clusters could be the Eu 2 O 3 and ZnO NPs in the synthesized nanocomposite [ 37 ].…”

Zinc oxide-ternary heterostructure Mn3O4/ZnO/Eu2O3 nanocomposites were successfully prepared via waste curd as fuel by a facile one-pot combustion procedure. The fabricated heterostructures were characterized utilizing XRD, UV–Visible, FT-IR, FE-SEM, HRTEM and EDX analysis. The photocatalytic degradation efficacy of the synthesized ternary nanocomposite was evaluated utilizing model organic pollutants of methylene blue (MB) and methyl orange (MO) in water as examples of cationic dyes and anionic dyes, respectively, under natural solar irradiation. The effect of various experimental factors, viz. the effect of a light source, catalyst dosage, irradiation time, pH of dye solution and dye concentration on the photodegradation activity, was systematically studied. The ternary Mn3O4/ZnO/Eu2O3 photocatalyst exhibited excellent MB and MO degradation activity of 98% and 96%, respectively, at 150 min under natural sunlight irradiation. Experiments further conclude that the fabricated nanocomposite exhibits pH-dependent photocatalytic efficacy, and for best results, concentrations of dye and catalysts have to be maintained in a specific range. The prepared photocatalysts are exemplary and could be employed for wastewater handling and several ecological applications.
