Hydrodechlorination of para chloroacetophenone with water-repellent platinum catalysts in a water/ethanol mixed solvent

- Modified Pt/SiO2 catalysts were prepared using water-repellent organosilane reagents.
- The hydrodechlorination of chloroacetophenone was examined by modified catalysts.
- Hydrophobic space on the modified catalyst improved the hydrodechlorination activity.
- More reactants in the aqueous solvent can interact with the hydrophobic space.
- An increasing in the numbers of collision between the reactants.
