Single-atom catalysts (SACs) involve atomically dispersed metal atoms on solid supports. SACs combine the fast reaction kinetics of homogeneous with recyclability heterogeneous catalysts, providing great technological opportunities. To date, SAC research has focused primarily development synthetic methods and fuel production. Here, we report a combination nanomotor design to fabricate motile systems, referred here as SAC-nanomotors. This concept is demonstrated by an Fe prepared via pulsing H2-pyrolysis approach. The SAC-nanomotor powered decomposing H2O2 ultrahigh-density atoms, achieving velocity 18 ± 3 μm s−1 at low concentration 10 mM. proof-of-principle SAC-nanomotor, smallest possible catalytic combustion site excellent biocompatibility, illustrates enormous potential for developing advanced systems.
