Johnson Matthey’s Sponge Metal Catalysts manufacturing site is located in Sevierville, Tennessee, USA, at the foothills of the beautiful Great Smokey Mountains. The production plants and laboratories are modern facilities capable of producing high quality alloy powders and activated catalysts with great consistency. The plant became ISO-9002 certified in 1993 and ISO9001-2000 certified in 2005.
Sponge Metal Catalysts are prepared from alloys of transition metals and Aluminium. The Aluminium is leached from the alloy structure, leaving behind an active metal surface covered or saturated with absorbed Hydrogen. The activated catalysts are stored under water to protect them from oxidation. Sponge Metal Catalysts are in a fully active form when shipped and require no preactivation prior to use.
