Reverse‐bumpy‐ball structure (RBBS) nanoreactors represent near‐ideal architectures for optimizing the performance of nanoparticle catalysts. Traditionally, RBBSs have been synthesized using laborious hard‐template methods. Herein, a novel and versatile synthetic strategy toward RBBS nanoreactors is developed by introducing high‐boiling‐point organics into a classical emulsion‐based nanocluster self‐assembly synthesis. This facile approach eliminates the need for a hard template and allows encapsulation of anisotropic nanoparticles in hollow nanoreactors. An RBBS nanoreactor containing Pt‐γ‐Fe₂O₃ dimers synthesized by this new approach demonstrates outstanding catalytic performance for the reduction of 4‐nitrophenol with H₂. The same strategy can easily be adapted for the synthesis of RBBS nanoreactors for other applications including catalysis, high‐performance batteries, drug delivery, sensors, and antimicrobials.

纳米晶体@中空硅反向颠簸-球形结构纳米反应器的通用微乳液模板化方法

反向颠簸球结构（RBBS）纳米反应器代表了近乎理想的体系结构，可优化纳米颗粒催化剂的性能。传统上，RBBS是使用费力的硬模板方法合成的。在此，通过将高沸点有机物引入经典的基于乳液的纳米簇自组装合成中，开发了一种针对RBBS纳米反应器的新颖且通用的合成策略。这种简便的方法消除了对硬模板的需求，并允许将各向异性的纳米粒子封装在空心纳米反应器中。含Pt-γ -铁的RBBS纳米反应器_2个ö ₃由这种新方法合成的二聚体演示4-硝基苯酚用H还原出色催化性能₂。可以很容易地采用相同的策略来合成RBBS纳米反应器，以用于其他应用，包括催化，高性能电池，药物输送，传感器和抗菌剂。
