Structured supports for noble catalytic metals: stainless steel fabrics and foils, and carbon fabrics

Conventional structured catalytic structures are constituted by a ceramic o r metallic monolith whose wall surface is covered by a porous coating on wh ich the active metal is deposited. To simplify the deposition procedures it is proposed to deposit the active metal on the bare surface of the carrier . The metal deposition is accomplished by the chemical reduction of metalli c ions in aqueous solution. Catalytically active systems obtained by anchor ing palladium (or ruthenium) on stainless steel supports or carbon fabrics are described. Their activity depends on the operating parameters of the de position procedure. (C) 2001 Elsevier Science BN. All rights reserved.
