Umpsy:
The catalyst used is platinum.
I apologize, it wasn't over your head.
I agree Platinum could be the catalyst. Other catalysts that could be doing the job include Ruthenium, Rhodium, Palladium, Vanadium, aluminoplatinum, etc., or even combinations of these. Does the company make any kind of claim as to the catalyst they are using?
