The surface of silica support was pretreated by various organic solvents before the impregnation of cobalt precursor. The catalysts prepared from pretreated supports exhibited highly catalytic activity, due to high dispersion and high reduction degree of the supported cobalt. Co/SiO₂ catalyst pretreated by acetic acid showed the highest CO conversion and the lowest CH₄ selectivity. The pretreatment by organic solvent modified the surface properties of silica support, realizing the high dispersion and the increased reduction degree of supported cobalt simultaneously. The properties of various catalysts were characterized by XRD, TPR and H₂ chemisorption.
