文摘
- •
Au-Pd alloy particles supported on/SiO2 with different surface structures were prepared.
- •
Few synergetic effect of Au-Pd alloy occurs on catalyzing CO oxidation.
- •
Alloying Au with Pd reduces the intrinsic activity in catalyzing CO oxidation.
- •
Contiguous Pd atoms on Au-Pd alloy are active in catalyzing CO oxidation while isolated Pd atoms are not.
