Preparation and structure of 3D ordered macroporous alloys by PMMA colloidal crystal templating

Abstract

Three-dimensionally ordered macroporous (3DOM) metal alloys of Ni_xCo_1−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.
