Abstract

In this work, ZnO particles with a unique dumbbell-shaped morphology with flower-like tips (DF-ZnO) were synthesized via the hydrothermal method. These particles measured 13.83 ± 2.35 μm in length and had tip diameters of 2.98 ± 0.89 μm. The DF-ZnO powders exhibited a hexagonal crystalline structure, as confirmed by XRD and Raman spectroscopy analyses. In addition to good stability and reusability, the DF-ZnO powders exhibited 88 % efficiency in the photocatalytic degradation of Eriochrome Black T (EBT) after 120 min of exposure to natural sunlight. Moreover, these particles exhibited antibacterial properties, with inhibition zones of 20 and 10 mm against Staphylococcus aureus and Escherichia coli, respectively.

水热法制备铃状花状ZnO的光催化性能及抗菌活性

在这项工作中，采用水热法合成了具有独特哑铃形状和花状尖端的ZnO颗粒（DF-ZnO）。这些颗粒的长度为13.83±2.35 μm，尖端直径为2.98±0.89 μm。XRD和拉曼光谱分析证实了DF-ZnO粉末具有六方晶体结构。除了具有良好的稳定性和可重复使用性外，DF-ZnO粉末在自然光照射120 min后光催化降解Eriochrome Black T （EBT）的效率为88%。此外，这些颗粒具有抗菌性能，对金黄色葡萄球菌和大肠杆菌的抑制区分别为20和10 mm。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
