Abstract

Sol–gel Co/SiO2 catalysts were prepared using Co–en (ethylenediamine) complex precursors with different cobalt introduction order. More highly reduced catalysts were obtained by gelling the silica support followed by depositing cobalt nanoparticles on silica surface, and then catalysts exhibited higher FT activity and concomitant higher C18+ selectivity. Meanwhile, both series of catalysts prepared with en/Co molar ratio of 2/1 exhibited higher activity due to their high cobalt reduction.
