Noble metal net for catalyzing gas phase reactions, production method for same, and use of same in an ammonia oxidation method

Abstract

The invention relates to a method for producing noble metal nets on flatbed knitting machines, the steps involving—providing noble metal wire comprising platinum—providing yarn that is combustible or soluble in solvent—knitting two-bed items by simultaneous knitting on the front and rear needle beds and joining the two knitted fabrics by means of connecting pile threads, wherein, on the front or on the rear needle bed, a combustible or soluble yarn is used which is burnt off or dissolved after the knitting process, and a noble metal wire is used on the other needle bed and for the pile threads such that, after the combustible or soluble yarn has been burnt off or dissolved, there remain only the pile threads and the knitted fabric made of noble metal wire and produced on the rear or front needle bed.
