摘要：

Fischer-Tropsch (F-T) reactions were carried out over mono- and bimetallic solvated metal atom dispersed (SMAD) catalysts. Supported Co, Fe, and Ni monometallic SMAD systems were compared, and Co exhibited the highest activity and showed no deactivation over 4 h. The Ni SMAD catalyst, especially on SiO//2, was the least effective owing to loss of Ni as Ni(CO)//4. The Fe SMAD catalysts were very selective for terminal linear alkene formation. Bimetallic Co-Mn and Fe-Mn systems were less active than monometallic Co or Fe systems. It is proposed that the presence of Mn allows the formation of stronger Co-CO bonds leading to lower reaction rates. However, the presence of MnO as a support caused an increase in hydrogenation activity. All catalysts exhibited Schultz-Flory behavior except the Co-Cr system.
