The influence of ethylenediamine (en)/Co molar ratio on the preparation of Co/SiO2catalysts was studied. The decomposition of these Co-en species resulted in the formation of small cobalt nanoparticles. The highly dispersed catalysts led to lower FT activity due to an increase of cobalt-silica interaction except Co(en)2/SiO2catalyst. Meanwhile, higher selectivity for light hydrocarbons was observed, which was ascribed that smaller cobalt particles containing active sites depressed the chain growth.
