Electronic interactions between metal nanoparticles and supports are the key to advanced catalytic materials. By combining model experiments and theory, we answer a long- standing question related to such interactions: What is the charge on a supported catalyst particle? We quantify the charge transfer for the practically important case of ceria-supported platinum particles and rationalize the origin of its size dependence.
