“…SEM images reveals that all samples consist of almost spherical shaped nanoparticles, no any indication of phase separation and little agglomeration was observed in sample though there is a sign of sample that might be as a result of gases like Co 2, N 2 and water vapor during the synthesis (Köseoğlu, 2016). A close view of all sample shows that smaller crystallites have sizes smaller than 100 nm which confirm the XRD results.…”

“…It can be observed that the most abundant element in both samples is Zinc then oxygen followed by the respective element. In both samples the appearance of un named peak at almost 2.0eV indicate the presence of carbon atom which result from the carbon coating applied before the Edx measurement (Köseoğlu, 2016). Moreover, from table 3 the percentage weight of each element is shown which is related with the number of elements in the sample similarly the atomic percentage of oxygen indicates that there is oxygen vacancies in both the sample's only that the vacancy is more presented in Ni 0.2 Co 0.1 Zn 0.7 O compared to ZnO sample which may result in increasing the ferromagnetic behavior of the samples (Sharma et al 2003).…”

ZnO and Ni 0.2 Co 0.1 Zn 0.7 O nanoparticles were successfully synthesized by microwave assisted combustion synthesis method using urea as a fuel. The structural, morphological, compositional and Magnetic property of Ni 0.2 Co (XRD), Scanning electron microscopes (FE (EDX), and quantum design Vibrating sample magnetometre structural property showed the formation of Wurtzite structure of ZnO,with nine prominent peaks in which the strong diffraction peaks appear in (100), (002) and (101), respectively, there is a trace related to Ni ions observed. The average size of these nanoparticles was estimat which show that there is a little decrease in the average size of the particles compared to ZnO. Scanning electron microscopes (SEM) showed that the samples have sizes smaller than 100nm, no indication of phase separation and little agglomeration was o spectroscopy (EDX) results tallies with the synthesis results. Magnetic measurement at all temperature the sample present a ferromagnetic behavior with a clear S shape hysteresis loop however the behavior is dec room temperature ferromagnetic behavior was maintained.

A Review of Microwave Synthesis of Zinc Oxide Nanomaterials: Reactants, Process Parameters and Morphologies

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.
