Palladium on carbon

From Wikipedia, the free encyclopedia

Palladium on carbon, often referred to as Pd/C, is a form of palladium used for catalysis. It is usually used for catalytic hydrogenations in organic chemistry. When the metal is distributed over finely-divided carbon catalyst support, the surface area is larger and the catalyst is more reactive.

Palladium-on-carbon has also been used as the palladium(0) catalyst in the Suzuki reaction, Stille reaction,[1] and related reactions.

Preparation[edit]

Palladium on carbon is commercially available, with a CAS number of 7440-05-3. It can also be prepared in the laboratory. In a typical procedure, a hydrochloric acid solution of palladium(II) chloride is treated with sodium acetate trihydrate followed by nitric acid-washed activated carbon. The palladium loading is typically between 5% and 10%.[2]
