Nanofoams are a class of nanostructured, porous materials (foams) containing a significant population of pores with diameters less than 100 nm. Aerogels are one example of nanofoam.[1]

Metal[edit]

In 2006, researchers produced metal nanofoams by igniting pellets of energetic metal bis(tetrazolato)amine complexes. Nanofoams of iron, cobalt, nickel, copper, silver, and palladium have been prepared through this technique. These materials exhibit densities as low as 11 mg/cm3, and surface areas as high as 258 m2/g. These foams are effective catalysts.[2]

Carbon[edit]

Carbon nanofoam is an allotrope of carbon discovered in 1997.[3] It consists of a cluster-assembly of carbon atoms strung together in a loose three-dimensional web. The material has a density of 2–10 mg/cm3 (0.0012 lb/ft3).[3][4][5]
