A catalytic material includes (i) a support material and (ii) a thin film catalyst coating having an inner face adjacent to the support material and an outer face, the thin film catalyst coating having a mean thickness of &#x2266;8 nm, and wherein at least 40% of the support material surface area is covered by the thin film catalyst coating; and wherein the thin film catalyst coating includes a first metal and one or more second metals, and wherein the atomic percentage of first metal in the thin film catalyst coating is not uniform through the thickness of the thin film catalyst coating.

Thin film catalytic material for use in fuel

A process for preparing a catalytic material including (i) a support material and (ii) a thin film catalyst coating, the coating including one or more first metals, wherein the process includes the steps of: providing a multilayer thin film coating of a second metal on the support material; and spontaneous galvanic displacement of at least some of the second metal with the one or more first metals; wherein the second metal is less noble than the one or more first metals.
