Abstract
A palladium-containing catalyst mat is made of a rolled PTFE-Kieselgur mixture which has been soaked with PdCl.sub.2 solution. It is made hydrophobic after soaking by treatment with a PTFE-Emulsion. Finally, it is subjected at about 430.degree. C. to a process which is similar to sintering and in which very finely divided Pd is produced through heat decomposition of the PdCl.sub.2. The catalyst mat is preferably combined with a carbon mat impregnated with CuO which, for example, may be a carbon felt which has been made denser through roller compression.
