面控合成的最新进展已经开始生产纳米晶体，作为下一代催化剂，具有很大的应用前景。然而，要从学术研究转向工业应用，必须解决通常以批量形式进行的合成的规模扩大问题。有两种相反的方法来扩大胶体纳米晶体的生产：增加和减少反应体积。与传统观点相反，基于液滴的连续流合成有望为按比例放大合成提供更实用的平台。在这里，我们重点介绍了使用液滴反应器合成具有可控尺寸和形状的胶体贵金属纳米晶体的最新进展，旨在实现大批量生产。
Recent progress in facet‐controlled syntheses has started to produce nanocrystals with great promise as the next‐generation catalysts for a variety of applications. To move from academic studies to industrial applications, however, one has to address the issue of scaling up a synthesis that has been commonly conducted in a batch format. There are two opposite approaches to scaling up the production of colloidal nanocrystals: increasing and decreasing the reaction volume. Contrary to conventional wisdom, continuous flow synthesis based on droplets is expected to provide a more practical platform for scaling up the synthesis. Here we highlight recent progress in using droplet reactors for the synthesis of colloidal noble‐metal nanocrystals with controlled sizes and shapes, with an aim towards high‐volume production.
