The crystal phase of metal nanocatalysts critically influences their catalytic performance, yet the atomic-scale mechanisms underlying their phase-dependent reactivity remain poorly understood. Using operando gas-cell transmission electron microscopy, here the authors directly correlate the crystal structure of Ru nanoparticles with their catalytic behavior during CO oxidation.
