Abstract
A layered catalyst including a surface axis including a catalyst material layer, and a substrate material layer contacting the catalyst material layer. The catalyst material layer includes a compressed atomic distance between two adjacent catalyst atoms along the surface axis relative to an atomic distance of the same catalyst material as in bulk. The substrate material has a higher surface energy than the catalyst material. In certain instances, at least 70 percent of total atoms of the catalyst material are in a film growth mode. In certain other instances, a surface free energy of the substrate material is 1 to 50 percent greater than a surface free energy of the catalyst material. In yet certain other instances, the catalyst material layer has a d-band center in a range of −2.1 eV to −2.25 eV.
