One of the methods for obtaining zinc oxide nanoparticles (ZnO NPs) is electrochemical synthesis. In this study, the anodic dissolution process of metallic zinc in alcohol solutions of LiCl was used to synthesize ZnO NPs. The products were obtained as colloidal suspensions in an electrolyte solution. Due to the small size and ionic nature of the zinc oxide molecule, colloidal nanoparticles tend to cluster into larger groupings, so the size of nanoparticles in solutions will differ from the size of nanoparticles observed in ZnO powders after solvent evaporation. The main goal of this research is to investigate the influence of the temperature of synthesis and the kind of alcohol on the size of ZnO NP micelles. Nanocrystals of zinc oxide were obtained in all tested alcohols: methanol, ethanol, and 1-propanol. The particle size was determined using the Dynamic Light Scattering (DLS) method. It was observed that the particles synthesized in methanol were the largest, followed by smaller particles in ethanol, while the smallest particles were obtained in 1-propanol. Additionally, the particles obtained in ethanol were the most uniform in size, showing the highest level of size homogeneity.
获得氧化锌纳米颗粒（ZnO NPs）的方法之一是电化学合成。在本研究中，利用金属锌在LiCl醇溶液中的阳极溶解过程来合成ZnO NPs。产物以胶体悬浮液的形式在电解质溶液中获得。由于氧化锌分子尺寸小且具有离子性质，胶体纳米颗粒倾向于聚集成更大的聚集体，因此溶液中纳米颗粒的尺寸将与溶剂蒸发后在ZnO粉末中观察到的纳米颗粒尺寸不同。本研究的主要目的是研究合成温度和醇的种类对ZnO NP胶束尺寸的影响。在所有测试的醇类（甲醇、乙醇和1-丙醇）中均获得了氧化锌纳米晶体。使用动态光散射（DLS）方法测定粒径。观察到在甲醇中合成的颗粒最大，其次是乙醇中的较小颗粒，而在1-丙醇中获得的颗粒最小。此外，在乙醇中获得的颗粒尺寸最均匀，显示出最高水平的尺寸均匀性。
