First‐Principles Calculation, Synthesis, and Catalytic Properties of Rh‐Cu Alloy Nanoparticles

The first synthesis of pure Rh(1−x)Cu(x) solid‐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 Rh(1−x)Cu(x) can be maintained even...

description The first synthesis of pure Rh(1−x)Cu(x) solid‐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 Rh(1−x)Cu(x) can be maintained even with 50 at % replacement of Rh with Cu. The prediction was confirmed for the catalytic activities on CO and NO(x) conversions.
