Platinum and catalysts

Hello, did someone already used a car catalytic converter as anode electrode or catalyst for chemical reactions?

i tried to found platinum here but is extremily expensive and hard to find, and a catalytic converter is easier and has rhodium and platinum

as a catalyst for a gas phase reaction sure it works, but as an anode? i don't thinks so.

the platinum/rhodium particles are dispersed on the surface of a porous ceramic matrix, to be used ad an electrode the surface must be conductive, maybe i'm wrong but i don't think that the surface of a catalytic converter is

Indeed, since there is no continuous metal surface and besides the metals mentioned, 3-way-cats also contain Pd.
