PREPARATION OF NANOPOROUS METAL FOAM FROM HIGH NITROGEN TRANSITION METAL COMPLEXES

摘要

Nanoporous metal foams are prepared by ignition of high nitrogen transition metal complexes. The ammonium salts of iron (III) tris[bi(tetrazolato)-amine], cobalt(III) tris(bi(tetrazolato)amine), and high nitrogen compounds of copper and silver were prepared as loose powders, pressed into pellets and wafers, and ignited under an inert atmosphere to form nanoporous metal foam monoliths having very high surface area and very low density.
