title: First-Principles Calculation, Synthesis, and Catalytic Properties of Rh-Cu Alloy Nanoparticles.
abstract: The first synthesis of pure Rh1-xCuxsolid-solution nanoparticles is reported. In contrast to the bulk state, the solid-solution phase was stable up to 750 °C. Based on facile density-functional calculations, we made a prediction that the catalytic activity of Rh1-xCuxcan be maintained even with 50 at % replacement of Rh with Cu. The prediction was confirmed for the catalytic activities on CO and NOxconversions.
