) but doesn't have palladium and not platinum.Palladium/Platinum Catalyst Preparation FAQ (https://www.thevespiary.org/rhodium/Rhodium/chemistry/pd-catalyst.faq.html)
(https://www.thevespiary.org/rhodium/Rhodium/chemistry/pd-catalyst.faq.html)and again, is there an other catalyst i could use instead of Pd and Ni ?
Probably some other weird and wonderfull transition metal compound.
There have been threads on palladium from catalytic converters etc, utfse. There are some other places that may order it for you... utf google.
As for prices, palladium is as its been said more expensive than gold, but you only need a tiny bit. Why dont you try and find Ni metal... its not hard, and less expensive than palladium.
