Beschreibung
Zusammenfassung:	An alloy catalyst for redox reaction which is capable of obtaining even superior catalytic activity comprises alloy particles of platinum and nickel, wherein the alloy particle is equipped at an outer surface with a crystal lattice plane represented by a Miller index {111}, and has an average particle diameter in a range of from 6 to 20 nm. The alloy particle preferably takes a shape selected from a regular octahedron, a truncated octahedron, a regular tetrahedron, and a truncated tetrahedron.
