The growth of nanoparticles is a complicated process, it depends on different factors in the reaction chamber, such as temperature, reagent concentration, duration, etc. The technological aspects play an important role in the dimensions and shape of nanoparticles, which affects its properties, especially when we have the nanoparticles of a semiconducting material.
In this article we have made an attempt to explore the influence of sodium chloride concentration and temperature of the electrolyte on the process of obtaining zinc oxide nanocrystals by the electrolytic method in an open electrolytic bath. The received samples were studied at room temperature by X-ray diffraction to determine its structure and dimensioning. The XRD pattern of samples exhibits a zinc-blended crystal structure. The nanocrystals dimensioning was made by using the Debye-Scherrer and Williamson-Hall methods, then the obtained results were compared. With the electrolyte temperature decreasing there were found new weak XRD peaks that do not belong to a wurtzite pattern, but do to the hydrozincite one. In the article a way of forming the hydrozincite using the atmospheric carbon dioxide is offered. It is also shown that the zinc oxide nanocrystals size decreases with a decrease of temperature of the electrolyte.
