FT special report: Cobalt nanoparticles with a size of around 7.7 nm prepared in 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imidate ionic liquids are effective catalysts for the Fischer–Tropsch (FT) synthesis, yielding olefins, oxygenates, and paraffins (C7–C30). The nanoparticles are easily prepared by the decomposition of [Co(CO)8] in the ionic liquid at 150 °C and can be reused at least three times if they are not exposed to air.
