摘要：
A method is provided for making a supported catalyst comprising nanostructured elements which comprise microstructured support whiskers bearing nanoscopic catalyst particles, where the method comprises the step of depositing a catalyst material comprising at least three metallic elements on microstructured support whiskers from a single target comprising at least three metallic elements. Typically, at least one of said metallic elements is Pt. In addition, one or more of said metallic elements may be Mn, Ni or Co. Other metallic elements or other transition metal elements may be included. In addition, the present invention provides a supported catalyst comprising nanostructured elements which comprise microstructured support whiskers bearing nanoscopic catalyst particles made according to the method of the present invention. Further, the present invention provides fuel cell membrane electrode assembly comprising the supported catalyst according to the present invention.
