Abstract
A method for fabricating a precious metal catalyst may include depositing a precious metal on a base material to form a catalyst structure, performing a first calcination on the catalyst structure, depositing a metal oxide on the catalyst structure such that the precious metal is at least partially encapsulated by the metal oxide, performing a second calcination on the catalyst structure, and reducing the catalyst structure with a reductive material to induce diffusion of at least a portion of the precious metal to a surface of the metal oxide.
