We demonstrate that small aqueous Pd-Au nanoparticles can hydrodechlorinate toxic trichloroethylene to inert ethane gas.  We seek to relate their nanostructure (as characterized through XAS and chemisorption) to their high activity (kcat > 5,500 L/gPd/min).  The observed structure effects in bimetallic catalysts may be extendable to other compositions and reactions.
