Abstract
A core-shell catalyst includes a porous, palladium-based core particle and a catalytic layer on the particle. The particle can be made by providing a precursor particle that has palladium interspersed with a sacrificial material. At least a portion of the sacrificial material is then removed such that the remaining precursor particle is porous.
