AB - IntroductionOpen‐cell metal foams are widely used in filters, heat pumps, heat exchangers, and substrates in catalysis due to a combination of their properties such as high thermal/electric conductivity with high specific surface area and permeability to liquids and gases.[1–3] In these applications, foams are often coated with active materials. The coating efficiency, based on open‐cell metal foams, depends on the total porosity, the cell size, and the specific surface area of the foams, which affect the loading with active material as well as the thermal and mechanical properties.[4,5]One of the manufacturing methods of highly porous open‐cell foams with high gas and liquid permeability is the sponge replication method.[4,6–8] In these foams, the shape of a polyurethane (PU) template foam is replicated and obtained by coating with a dispersion of the respective material and subsequent thermal processing. These replicated foams have a high specific surface area, which can be adjusted by the cell size of the PU template foams. After the burn‐out of the template, hollow struts are formed, which is a distinctive feature of replicated foams in comparison with structures made by other manufacturing methods. These strut cavities, in turn, lead to an increase in the specific surface area.
