“…Figure 11 , shows that there was no apparent reduction in the photo-degradation efficiency even after repeated use. This illustration is based on the structural stability of the hybrid photocatalyst coupled with the catalytic activity of semiconductor nanoparticles [ 83 ]. It was observed that the reduction in the rate of photocatalytic degradation after the 10 th cycles was less than 4% (from 98% to 94%) for ZnO.…”

Herein, CuO/ZnO nanocomposites at different ratios were successfully synthesized through a green biosynthesis approach. This was performed by harnessing the fungal-secreted enzymes and proteins during the sol-gel process for nanocomposites seed growth. All fabricated nanoparticles/nanocomposites were characterized using Fourier Transform Infra-Red (FT-IR) Spectroscopy, X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM-EDX) and X-ray Photoelectron Spectroscopy ( XPS) analyses. The photocatalytic degradation efficacy of the synthesized nanocomposites was evaluated using a cationic methylene blue (MB) dye as a model of reaction. Results obtained from the FT-IR and EDX analyses revealed that CuO-NPs, ZnO-NPs, CuO/ZnO 50/50 , CuO/ZnO 80/20, and CuO/ZnO 20/80 were successfully prepared by harnessing the biomass filtrate of Penicillium corylophilum As-1. Furthermore, XRD and TEM revealed the variation in the particle size of the nanocomposites (10–55 nm) with the ratio of the nanoparticles. Notably, the size of the nanocomposites was proportionally increased with an increasing ratio of ZnO-NPs. XPS analysis affirmed the presence of both Cu and Zn in the nanocomposites with varying binding energies compared with individual nanoparticles. Furthermore, a high photo-degradation efficacy was achieved by increasing the ratio of ZnO-NPs in the nanocomposite formulation, and 97% of organic MB dye was removed after 85 min of irradiation using the CuO/ZnO 20/80 nanocomposite.

“…YVO 4 had a zircon structure, which nucleated as a tetragonal prism and tetragonal dipyramid growth unit. [ 25,26 ] In addition, a crystalline structure similar to that of YbVO 4 was found. [ 27 ] The corrosion products were the same at different corrosion temperatures.…”

“…The morphology of YVO 4 formed by the former was a square prism, whereas that formed by the latter was mainly particleshaped. According to the literature, [25,27] YVO 4 is a zircon structure, and its crystal structure is a square prism with square cones at both ends (Figure 14). The crystal structure was consistent with the morphology of YVO 4 formed by the corrosion of NaVO 3 .…”

The hot corrosion behaviour of the γ-Y 2 Si 2 O 7 ceramic exposed to NaVO 3 or V 2 O 5 molten salt was studied at 1000-1300°C. YVO 4 was identified as the corrosion product due to the chemical interaction of the two corrosive agents with the γ-Y 2 Si 2 O 7 ceramic. Although YVO 4 produced in the two corrosion reactions had the same crystallographic structure, they had different morphologies. YVO 4 produced by the corrosion of NaVO 3 with the γ-Y 2 Si 2 O 7 ceramic showed a rod-like shape, whereas it was particle-shaped in the corrosion reaction of V 2 O 5 with the γ-Y 2 Si 2 O 7 ceramic. Additionally, the degradation of γ-Y 2 Si 2 O 7 ceramic by V 2 O 5 was more severe than that by NaVO 3 , and the thickness of the corrosion layer significantly increased with temperature. In this study, a model describing the formation of the corrosion product was established, and the formation of YVO 4 with different morphologies in the two corrosion reactions was explained based on the growth characteristics of the YVO 4 crystals.

“…An example of a binary system constituting one cross-section of a ternary system of V 2 O 5 -Yb 2 O 3 -Y 2 O 3 oxides is the YVO 4 -YbVO 4 system . Yttrium orthovanadate(V) and ytterbium are well characterized in the literature [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46].

The main objective of this work was to experimentally confirm that a continuous, substitutional solid solution of a general formula Y1−xYbxVO4 is formed in the pseudo-binary system YVO4–YbVO4, and to investigate its basic unknown properties as a function of composition for 0.00 < x < 1.00. To date, such a solid solution has been obtained and characterized to a limited extent, but only for a few selected compositions. This solution was obtained by a high temperature and, for the first time, using mechanochemical methods. For the solution obtained by the high-energy ball-milling method, unknown physicochemical properties were established over its entire range of homogeneity. The solution was synthesized from mixtures of yttrium orthovanadate (V) with ytterbium (III) orthovanadate (V) of different compositions and investigated by XRD, IR, SEM, and UV-Vis(DRS) methods. It was found that Y1−xYbxVO4 crystallizes in a tetragonal system. The results confirmed that the solid solution Y1−xYbxVO4 has a structure of YVO4 and YbVO4, and its structure is composed of YbO6 and YO6 octahedrons and VO4 tetrahedrons. Moreover, if the parameter (x) in the solid solution Y1−xYbxVO4 increases, its crystalline lattice contracts and the value of the energy gap decreases. This solid solution is stable in the air atmosphere at least up to ~1500 °C. The estimated band gap for this solid solution indicates that it belongs to the semiconductors.
