9. A catalyst material including a bulk material and a doping material, the catalyst material comprising:
a polyhedron structure including
a first surface facet having a first surface layer and at least one first subsurface layer, the first surface layer including the bulk material, and the at least one first subsurface layer including a doping material with a first subsurface concentration;
a second surface facet having a second surface layer and at least one second subsurface layer, the second surface layer including the bulk material, and the at least one second subsurface layer including the doping material with a second subsurface concentration less than the first subsurface concentration; and
a third surface facet having a third surface layer and at least one third subsurface layer, the third surface layer including the bulk material, and the at least one third subsurface layer including the doping material with a third subsurface concentration less than the second subsurface concentration.
