ABSTRACT:
The present invention is a method to activate a noble metal complex dispersed on a catalyst support comprising calcining in hydrogen in order to decompose and reduce the noble metal complex in a single step. In a preferred embodiment, the noble metal catalyst is a combination of platinum and palladium and the noble metal complexes are the hydroxides.
