Plasma pretreatment of cobalt Fischer–Tropsch catalysts through glow discharge decomposes cobalt nitrate at much lower temperatures than conventional calcination, and smaller superparamagnetic Co metal particles (<7 nm) are formed (see schematic representation). The Fischer–Tropsch reaction rates with these catalysts are higher than or comparable to those of their counterparts prepared by conventional calcination at 473 K.
