Abstract

Zinc oxide nanoparticles (ZnO NPs) were successfully synthesized by a green method using rosin and zinc chloride as salt precursors. The phase structure, morphology, and particle size of ZnO were determined by X-ray powder diffraction, field emission scanning electron microscopy, and high-resolution transmission electron microscopy. The fabricated ZnO NP samples are crystalline with a grain size of 30-100 nm. The ZnO NPs were used as catalysts for the photodegradation of methylene blue (MB) and methyl orange (MO) under visible and UV light. The results indicate that the prepared ZnO material excellently removed MB and MO ( = 10 mg/L) with efficiencies of 100% and 82.78%, respectively, after 210 min under UV radiation with a ZnO NP dose of 2 g/L. The photocatalyst activity of the synthesized material was also tested under visible light radiation with the same conditions; however, it achieved lower efficiencies. In addition, ZnO NPs were also tested regarding their antibacterial activity, and the results showed that the prepared ZnO samples had the highest (i.e., 100%) antibacterial efficiency against .

摘要

采用绿色方法，以松香和氯化锌作为盐前驱体，成功合成了氧化锌纳米颗粒（ZnO NPs）。通过X射线粉末衍射、场发射扫描电子显微镜和高分辨率透射电子显微镜确定了ZnO的相结构、形态和粒径。制备的ZnO NP样品为晶体，晶粒尺寸为30 - 100 nm。ZnO NPs用作可见光和紫外光下亚甲基蓝（MB）和甲基橙（MO）光降解的催化剂。结果表明，在2 g/L ZnO NP剂量的紫外辐射下210分钟后，制备的ZnO材料分别以100%和82.78%的效率出色地去除了MB和MO（初始浓度 = 10 mg/L）。在相同条件下的可见光辐射下也测试了合成材料的光催化活性；然而，其效率较低。此外，还测试了ZnO NPs的抗菌活性，结果表明制备的ZnO样品对[具体菌种未给出]具有最高（即100%）的抗菌效率。
