Abstract
A method and device for catchment of platinum group metals (PGM) in a gaseous steam, where the method comprises using a catalyst comprising a porous ceramic body in which at least a part of the surface area is covered by one or more PGM-catching metal(s)/alloy(s), and where the device comprises the porous ceramic body in which at least a part of the surface area is covered by one or more PGM-catching metal(s)/alloy(s). In a further aspect, the invention also relates to a method for producing the inventive device.
