摘要：

Colloidal cobalt nanoparticles with well-defined particle size (ca. 2.7 nm) were synthesized, characterized, and tested in Fischer-Tropsch synthesis (FTS) using water and binary mixtures as solvent. The catalytic results revealed that activity and selectivity strongly depend on the nature and composition of the solvent mixture: the tests in pure water produced light hydrocarbons (C-2-C-4), while the addition of organic cosolvents increased the activity and shifted the selectivity to higher hydrocarbons (C-13-C-30). The observed variations in the activity and selectivity were correlated to syngas solubility in the medium used for catalysis. Under the tested conditions, ethanol/water (93/7 v/v) appeared to be the optimum binary solvent in terms of FT activity.
