A new and general way to prepare porous metals with highly ordered 3D arrays of void spaces is reported here. The technique involves filling the spaces between colloidal crystals in a 3D array with a metal ion solution, and removing the solvent to produce a salt skeleton. The skeleton then undergoes chemical transformation to produce a metallic framework, such as that of Ni (shown in the Figure), with pore sizes of a few hundred nanometers.
