Activated charcoal, also known as activated carbon, is a highly porous form of carbon that has been processed to have a large surface area and numerous internal pores. Palladium on activated charcoal refers to palladium metal nanoparticles deposited onto the surface of activated charcoal. This combination serves as a versatile and efficient catalyst in various chemical reactions.

Palladium on activated charcoal is widely used in the chemical industry as a heterogeneous catalyst. It is particularly valuable in hydrogenation reactions, where it facilitates the addition of hydrogen atoms to unsaturated organic compounds, such as alkenes and alkynes. This catalytic process is essential in the production of a wide range of chemicals, including pharmaceuticals, petrochemicals, and fine chemicals. Palladium on activated charcoal offers several advantages, such as high catalytic activity, ease of separation from reaction mixtures, and reusability. Its versatility and efficiency make it a valuable tool for chemists and chemical engineers involved in organic synthesis and industrial processes.
