Hydrogenation of ketones over bifunctional Pt-heteropoly acid catalyst in the gas phase

- Gas-phase hydrogenation of ketones to alkanes via bifunctional metal-acid catalysis studied.
- Catalyst activity decreases in the order: Pt > Ru >> Ni > Cu.
- Pt/CsPW gives almost 100% alkane yield at 100 °C and 1 bar pressure.
- The rate-limiting step established.
