A scalable synthesis of core/shell capsules by the heat treatment of polyelectrolyte‐multilayer‐particle reactors, in which metal nanoparticles are embedded (see figure), is demonstrated. Using this method, it is possible to prepare a wide variety of core/shell structures from a variety of materials, and to control the size, dispersity, and core composition of mono‐ or bimetallic core particles.
