摘要：

A simple test reaction has been developed for the qualitative determination of the efficiency of platinum re-reduction or to show the presence of adsorbed oxygen on supported Pt catalysts. The method is based on the surface reaction taking place between tin tetraethyl and unreduced platinum or adsorbed oxygen. The formation of ethylene in the above reaction indicates that supported platinum catalyst contains either unreduced platinum or adsorbed oxygen.
