Preparation of Co/SiO2 Using Several Glycols for Enhanced Fischer-Tropsch Synthesis Activity and Dispersion of Co-0 Nanoparticles with Unique Co-0 Particle Size Effect
Co/SiO2 catalysts with highly dispersed Co-0 and reducible Co were prepared by impregnation using an aqueous solution of Co nitrate containing ethylene glycol or its homologs. Addition of glycols enhanced FTS activity by a factor of 4. Particle size of Co-0 decreased from 30 to below 6 nm, while TOF of the catalysts was independent of the Co-0 particle size.
