Abstract

Three-dimensionally ordered macroporous (3DOM) metal alloys of NixCo1−x (a solid solution) and Mn3Co7 (an intermetallic compound) have been prepared by templated precipitation of mixed metal salts within colloidal crystals of poly(methyl methacrylate) spheres and subsequent chemical conversion of the inorganic precursors.
