Abstract: tCobalt nanoparticles in the range of 1.7¿7 nm were synthesized in water using sodium borohydride asreducing agent and subsequently immobilized on TiO2. Both colloidal and TiO2supported NPs were char-acterized by TEM, XRD, HRTEM, XPS, TGA, ICP techniques and their catalytic performance of the supportedcatalysts evaluated in the Fischer¿Tropsch synthesis. As a general trend, an increase in activity and TOFwas observed when the particle size decreased. These results were rationalized by the higher reducibilityof the catalysts bearing the smaller nanoparticles. The unconventional stability of these relatively smallCoNPs in FTS was attributed to the promoting effect of boron on the stability of the cobalt nanocrystals
