“…The increase in the spin-orbit energy after SrSnO3 deposition indicates a perturbation in the local environment around the Sr and reinforces the suggestion of a Sr-O-Zr interface composition in SrSnO3@ZrO2. In addition to that, the Zr 3d XPS (Figure 4e) shows that the Zr 3d core level splits into Zr3d5/3 and Zr3d3/2 levels and the estimated spin-orbit splitting of ΔE = 2.32 eV reveals that the valence state of Zr is 4+ at the interface of SrSnO3@ZrO2 sample [42,43]. The high intensity of Sn 3d (Figure 4c) and O 1s (Figure 4d) peaks in the XPS spectra indicates that Sn-O environments are prominent at the surface of both materials as expected and in good accordance with [13,41].…”

ZnO nanoplates and ZnO nanostructure flowers were successfully synthesized in alkaline solutions containing different contents of sodium hydroxide by a cyclic-microwave method. The as-synthesized products were characterized by X-ray Diffraction, Field Emission Scanning Electron Microscopy and ultraviolet (UV)visible spectroscopy. The crystal structure of ZnO nanoplates and nanostructure flowers are wurtzite structure with energy band gap of 3.2013.217 eV. In this research, these products were applied as energy harvesting materials in dye sensitized solar cells (DSSCs) and also used photocatalytic degradation of methylene blue (MB) under UV irradiation. In the case of photo conversion materials, the DSSCs based ZnO nanoplates showed the best performance of photoconversion to electricity at 1.5 AM illumination. Moreover, it also well performed at dye degradation of MB under UV irradiation.

Zinc oxide (ZnO) is a multifunctional material due to its exceptional physicochemical properties and broad usefulness. The special properties resulting from the reduction of the material size from the macro scale to the nano scale has made the application of ZnO nanomaterials (ZnO NMs) more popular in numerous consumer products. In recent years, particular attention has been drawn to the development of various methods of ZnO NMs synthesis, which above all meet the requirements of the green chemistry approach. The application of the microwave heating technology when obtaining ZnO NMs enables the development of new methods of syntheses, which are characterised by, among others, the possibility to control the properties, repeatability, reproducibility, short synthesis duration, low price, purity, and fulfilment of the eco-friendly approach criterion. The dynamic development of materials engineering is the reason why it is necessary to obtain ZnO NMs with strictly defined properties. The present review aims to discuss the state of the art regarding the microwave synthesis of undoped and doped ZnO NMs. The first part of the review presents the properties of ZnO and new applications of ZnO NMs. Subsequently, the properties of microwave heating are discussed and compared with conventional heating and areas of application are presented. The final part of the paper presents reactants, parameters of processes, and the morphology of products, with a division of the microwave synthesis of ZnO NMs into three primary groups, namely hydrothermal, solvothermal, and hybrid methods.
