Abstract Catalysts made of in-situ exsolved metal nanoparticles often demonstrate promising activity and high stability in many applications. However, the design of these catalysts is greatly constrained by the classic exsolution mechanism, which occurs almost exclusively through substitutional metal-doping in perovskites. Here we show that metal nanoparticles can also be in-situ exsolved from interstitially doped metal cations in a NiOOH supporting framework with the guidance of theoretical calculation. The exsolution can be conducted swiftly at room temperature. A novel copper nanocatalyst prepared with this approach have a quasi-uniform size of 4 nm delivering an exceptional CO faradaic efficiency of 95.6% with a notable durability for the electrochemical reduction of CO2. This design principle is further proven to be generally applicable to other metals and foregrounded for guiding the development of advanced catalytic materials.
