What is special about platinum structure which actively participate in catalytic reactions while similar metals with similar atomic structures cannot.

  • $\begingroup$ Indeed, similar metals with similar structures ($\ce{Pd,\;Ir}$) are just about as good in many catalytic reactions, so $\ce{Pt}$ is not all that exceptional. $\endgroup$ Apr 16, 2016 at 13:37

    $\begingroup$ @IvanNeretin Righto. The whole cluster of them has a name: Platinum group metals $\endgroup$
