thinking about SO3 generation I was looking for platinum catalysts on ebay and found these

obviously not much platinum content judging by the price,
anyone have any experience or opinions ?

Go for Vanadium oxide instead of platinum, better for your wallet

"Iron oxide" is even cheaper.

As for the eBay item, NurdRage and more than one active member here have been ripped off by fake "platinum" products from eBay.

Wow those are cheap. If they do contain platinum as you suggest it will not be very much. Wiki suggested they contain platinum but I could not find any dissection info on them to confirm that.

Years ago you could get a glow wire type gas stove lighter It used a large drycell to heat a small platinum (allegedly) filament to a barely perceptible dull red heat. When placed in the gas stream it would glow brightly and then ignite the gas. I keep an eye out looking for a discarded one in charity shops and recyclers.

They also make a butane powered curling tongs that use a catalyst. Possible this is one https://www.amazon.co.uk/BaByliss-2585U-Large-Cordless-Style...
They use a battery powered filament to initially heat up the catalyst. Perhaps they have little platinum in them too.

You could buy these:

The disc at the bottom is a piece of moulded plastic with a platinum powder on it. Again, I don't know how much platinum there is but there is at least some.
