Breakdown of the Structure–Function Relationship on a Polycrystalline Pd Catalyst Surface Illustrated by Dynamic CO Oxidation
Real catalysts consisting of nanoparticles host many nanofacets. Each nanofacet changes its structure and function in response to its local environment but is also affected by neighboring nanofacets. Time-resolved operando experiments close to realistic conditions at polycrystals mimicking real catalyst particles are unfortunately challenging but could be highly rewarding. Here, we demonstrate how
