The present work proposes a method for fabricating metallic zinc (Zn) nanoparticles in aqueous solution. An aqueous colloidal solution of metallic Zn nanoparticles was prepared from Zn acetate by electrolysis under ultrasonic irradiation in water. Transmission electron microscopy and X-ray diffractometry revealed that metallic Zn nanoparticles with a crystal structure of hexagonal and a particle size of ca. 130 nm were produced using carbon bars as electrodes. However, the carbon that peeled off with the ultrasonic irradiation was included in the nanoparticles. High-purity metallic Zn nanoparticles with sizes of 30–90 nm could be fabricated using metallic Zn plates as the electrodes. The metallic Zn nanoparticles were chemically stable in both aqueous solution and the atmosphere. The chemically-stable metallic Zn nanoparticles are expected to be applied to catalyst, fabrication of alloy nanoparticles composed of Zn and other metals, anti-rust paint, etc.

电解合成金属锌纳米粒子

本工作提出了一种在水溶液中制备金属锌(Zn)纳米颗粒的方法。在水中超声照射下通过电解由乙酸锌制备金属锌纳米颗粒的胶体水溶液。透射电子显微镜和X射线衍射分析表明,金属Zn纳米颗粒的晶体结构为六边形,粒径约为。使用碳棒作为电极产生了130 nm。但是,通过超声波照射剥离的碳被包含在纳米粒子中。使用金属锌板作为电极可以制造尺寸为30–90 nm的高纯度金属锌纳米粒子。锌金属纳米粒子在水溶液和大气中均具有化学稳定性。
