Randomly alloyed noble metal nanoparticles with unusual compositions may be prepared as 'stable' entities on the nanoscale using microwave-assisted solution synthesis.  Bimetallic and ternary alloys of classically immiscible metals (e.g., RhAg, RhAu and IrAg) and metastable alloys (e.g., RhPd and RhPdAu) have been prepared, and their catalytic propoerties studied as a result of relative composition.  Complimentary theoretical studies help to explain the relationsship between surface structure and reactivity in alkene hydrogenation chemistry.  Using the tools-of-the-trade taught to us by Prof. Gabor Somorjai, we present some new and unexpected results.
