General description

Activated charcoal (AC) or activated carbon acts as an adsorbent, which is used to remove a broad spectrum of pollutants in air, water, and soil.[1][2] It can be produced by carbonization of materials like coal and lignocellulosic biomass under an inert atmosphere.[3] AC in combination with palladium is used as a catalyst in the hydrogenation of alkenes, alkynes, ketones, nitriles, imines, nitro groups, aromatic and heteroaromatic systems.[4]

Application

Activated charcoal can be used:
  • As a promoter in combination with K2S2O8 for the synthesis of ketones and aldehydes through oxidation of alcohols.[5]
  • Along with H2SO4 for the preparation of 3,4-dihydropyrimidin-2-(1H)-ones and its derivatives.[6]
  • In combination with NaBH4 for the reduction of nitroarenes to amines.[7]
