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.

“…Peak around 400 nm is near band emission peak attributed to radiative recombination of free excitons from the bottom of the V 3d conduction band to the top of the O 2p valance band. [42][43][44] Also, the recombination of excitons from V 3d splits off conduction band to the top of O 2p valance band, which causes the PL spectrum to peak at around 450 nm. [45] Peak around 560 nm belongs to a defectrelated peak, oxygen vacancies, which is derived from the lowest defect donor band to O 2p valance band in V 2 O 5 nanoparticles.…”

Different molar concentrations (0.05-0.2 M) of vanadium pentoxide nanoparticles were synthesized with and without polyvinylpyrrolidone (PVP) using hydrothermal method. The growth mechanism with different molar concentrations as well as the effect of PVP on the structural, optical, and electrical properties have been investigated. The size of the particles was measured from transmission electron microscopy (TEM) and x-ray diffraction spectroscopy (XRD). Optical properties were analyzed through photoluminescence and absorption measurement. The electrical transport properties were analyzed by impedance spectroscopy and Van der Pauw method. From impedance measurements, dominance of grain boundary resistance over grain resistance was observed. The resistivity also decreased with increasing molar concentrations of nanoparticles with and without PVP. The highest temperature coefficient of resistance (TCR) value of À 2.33 %/K with the lowest resistivity of 0.02 Ω. cm for V 2 O 5 nanoparticle of 0.2 M concentration without using PVP was observed. Therefore, such V 2 O 5 nanoparticles are a potential material for microbolometer applications.

“…However, all of these attributes can be directly influenced by the nature, structure, size and, most importantly, morphology of the constituent nanostructure. Among others, zinc oxide (ZnO) nanoparticles (NPs) have been extensively studied for gas sensing, [18] in solar cells [19] and for photo‐electrocatalysis [20] etc. The most attractive feature of ZnO lies in the association of its chemical and physical properties with its morphology and particle size [21–23] …”

Zinc Oxide Nanoparticles as Antifouling Materials for the Electrochemical Detection of Methylparaben

et al. 2021

View full text Add to dashboard Cite

The use of personal care products (PCPs) containing methylparaben (MePa) has been linked with coral reef damage, breast cancer, and endocrine disruption. To monitor such pollutants, the development of simple, fast, and sensitive detection methods is needed. This study reports the electrochemical detection of MePa using a zinc oxide (ZnO) nanoparticle modified glassy carbon electrode. We addressed two main challenges posed by the use of sensing electrodes, that is, the instant fouling of electrodes for the detection of phenolic compounds and the use of expensive or highly complex, multicomponent materials for the detection of water contaminants. By controlling the pH of the reaction solution, ZnO nanoparticles with three different morphologies were synthesized: nanowires, nanocuboids, and nanospheres. The impact of these morphologies on the performance and sensitivity of the fabricated modified electrode was investigated. Under optimum conditions, ZnO nanowires demonstrated the best response compared to the other geometries, with a linear calibration response in the range of 0.02–0.12 mM, and the lowest limit of detection (LOD) of 7.25 μM. The proposed sensor not only offers simplicity and the use of low‐cost materials, but also successfully overcomes the electrode passivation associated with phenol‐containing chemicals and can, therefore, be an attractive candidate for further antifouling applications.
