Abstract
A simple test reaction has been developed for the qualitative determin ation of the efficiency of platinum re-reduction or to show the presen ce of adsorbed oxygen on supported Pt catalysts. The method is based o n the surface reaction taking place between tin tetraethyl and unreduc ed platinum or adsorbed oxygen. The formation of ethylene in the above reaction indicates that supported platinum catalyst contains either u nreduced platinum or adsorbed oxygen.
