Cu meatball-like spheres are prepared by a simple approach and used to obtain Au–Cu meatball-like cages with hollow interiors and porous shells by a galvanic replacement reaction. Characterization indicates that the particles, whose morphology holds promise for catalysis applications, are not comprised of an alloy but rather of discrete copper and gold regions. The bimetallic cages show strongly enhanced activity towards carbon monoxide (CO) oxidation reaction at low temperatures.
