文摘
- •
Au@FeOx dumbbell nanocrystals with 4, 6 and 10 nm Au domain successfully synthesized.
- •
Enhanced activity in CO oxidation, good sintering resistance and good stability.
- •
Dumbbells with 4 nm Au domains were found to be the most active ones.
- •
Iron oxide coating of Au NCs responsible for the limited TOF in 4 nm Au@FeOx dumbbells.
