论文摘要
金属纳米颗粒在不同的科学领域(例如光化学,能量转化和医学)产生了重大影响。在常用的纳米颗粒中,银纳米颗粒具有特别感兴趣,因为它们的抗菌特性以及在感应和催化中的应用。但是,用于合成银纳米颗粒的许多方法通常不会导致定义明确的产品,主要障碍是高多分散性或缺乏粒度可调性。我们描述了使用多元途径的平均半径为3和5 nm的可调颗粒的按需合成的自动方法。多元元过程是银纳米颗粒的有前途的途径,例如用作参考材料。我们使用小角度X射线散射,动态光散射和进一步的方法表征了合成的纳米颗粒,表明自动合成可以产生具有可重复可调节特性的胶体。
Metal nanoparticles have a substantial impact across different fields of science, such as photochemistry, energy conversion, and medicine. Among the commonly used nanoparticles, silver nanoparticles are of special interest due to their antibacterial properties and applications in sensing and catalysis. However, many of the methods used to synthesize silver nanoparticles often do not result in well-defined products, the main obstacles being high polydispersity or a lack of particle size tunability. We describe an automated approach to on-demand synthesis of adjustable particles with mean radii of 3 and 5 nm using the polyol route. The polyol process is a promising route for silver nanoparticles e.g., to be used as reference materials. We characterised the as-synthesized nanoparticles using small-angle X-ray scattering, dynamic light scattering and further methods, showing that automated synthesis can yield colloids with reproducible and tuneable properties.
