Mono‐ and multimetallic nanoparticles (NPs) have diverse and tunable physicochemical properties that arise from their compositions as well as crystallite size and shape. The ability to control precisely the composition and structure of NPs through synthesis is central to achieving state‐of‐the‐art designer metal NPs for use as catalysts and electrocatalysts. However, a major limitation to the use of designer metal NPs as catalysts is the ability to scale their syntheses while maintaining structural precision. To address this challenge, continuous flow routes to metal NPs involving the use of droplet microreactors are being developed, providing the synthetic versatility necessary to achieve known and completely new nanostructures. This progress report outlines how the chemistry and process parameters of droplet microreactors can be used to achieve high performing nanocatalysts through control of NP composition, size, shape, and architecture and outlines directions toward previously unimaginable nanostructures.

通往设计师金属纳米催化剂的连续流动路线

单金属和多金属纳米颗粒（NPs）具有多种多样且可调节的物理化学性质，这些性质是由其组成以及微晶的大小和形状引起的。通过合成精确控制NP的组成和结构的能力对于获得用作催化剂和电催化剂的最先进的金属NP至关重要。但是，将设计金属NP用作催化剂的主要限制是在保持结构精度的同时能够扩展其合成规模。为了应对这一挑战，正在开发涉及使用液滴微反应器的连续的金属NP流路，从而提供实现已知和全新纳米结构所需的合成多功能性。
