Metals: Physicochemical Properties for Catalytic Conversions

[fysik]

hello!

what are the physicochemical properties of the metals that facilitate the catalytic conversion in cars?

what are their properties that make them act the way they do? ie. facilitate the reactions?

I mean in electron/proton etc basics, atomic level

thanks

can't anyone at least find for me this info online? I can't find anything!

anyone? so many scientists and no one can answer?
