- •
Pt, Ru and Ir-catalysts were developed by impregnation of a microporous carbon xerogels.
- •
Sintering is favoured after H2 pre-treatments regarding He pre-treatments, mainly for Ru-catalysts.
- •
Ir-catalysts present a low activity but a high selectivity to unsaturated alcohols.
- •
Pt-catalysts present the best combination of activity and selectivity, but a deeper deactivation by CO -poisoning.
