Supported metal oxides, metals and sulfides form a large fraction of industrially important catalysts.    Preparation of supported catalysts can involve a rich chemistry.  We will detail different preparation approaches all aimed at controlling active site number and site location, particularly on bimetallic noble metal supported catalysts.  Issues involving activity, transport, metal mixing and deactivation come into play.  Site locations are optimized on both mm and nm scale.  The primary approach we will illustrate involves surface complex formation using bifunctional organic chelating agents.  We will show specific examples for making supported bimetallic Pt-Pd and Ru-Rh catalysts on silica.<br/>
