Palladium on carbon, often referred to as Pd/C, is a form of palladium used as a catalyst in hydrogenations.

General

The palladium metal is supported on activated carbon in order to maximize its surface area and activity.

How to use Pd/C

To be added

A video showing the procedure can be found here.

Availability

Pd/C is sold by various lab suppliers.

Preparation

Palladium chloride and hydrochloric acid are added to a warmed, aqueous suspension of activated carbon. Formaldehyde is then added to the solution followed by neutralization with sodium hydroxide. Finally the catalyst filtered, washed with distilled water, and dried over potassium hydroxide. Palladium loading is typically between 5% and 10%.

Projects

  • Catalytic hydrogenation (reductive amination, carbonyl reduction, nitro compound reduction, the reduction of imines and Schiff bases, debenzylation reactions, etc.)
  • Coupling reactions (Suzuki reaction, Stille reaction, etc.)

Handling and safety

Pd/C is highly reactive due to its high surface area, and when filled with hydrogen it may ignite in contact with oxygen.
