H2O2 direct synthesis under mild conditions on Pd-Au samples: Effect of the morphology and of the composition of the metallic phase

- H2O2 direct synthesis under mild and non explosive conditions on Pd-Au/silica.
- Best catalytic results introducing Au and Pd by incipient wetness co-impregnation.
- The productivity follows the trend: PdAuSi ≈ PdAuSZ > PdAuZ >> PdAuCe ≈ PdAuSCe.
- A PdAuO phase indicates the presence of less energetic sites favouring H2O2.
- Presence of more energetic sites on ceria leading to the formation of water.
