Synthesis and stabilization of ultrasmall metal nanocrystals at high temperature have always been challenging due to their self‐aggregating behavior. Here, we introduce a strategy to synthesize a cluster of tiny metal nanocrystals (~3 nm) inside a hollow carbon shell as yolk@shell‐type architecture following a metal‐coordination‐based nanocrystal stabilization at high temperature (500 ° C). The successful catalytic reduction of 2‐amino‐4‐nitrophenol demonstrates the efficiency of such nanoreactor in chemical transformation. Further adaptation of this strategy helps in synthesizing bimetallic (Au/Pt, Au/Pd, and Au/Ru) nanocrystals, which unfolds the possibilities to design advanced new‐generation catalysts.
