- •
Pd/C catalysts were prepared by coating AC onto the surface of Pd colloids containing ternary surfactants.
- •
Brij 35-Tween 80-CTAB ternary surfactants provide a dense micellar layer which warps and minimizes the colloids particles.
- •
The catalyst performance is relatively nice when the concentration of surfactants is 0.67 g/L.
- •
Catalyst nearly remains stable after five consecutive hydropurification tests.
