A new metal-organic framework compound formulated as [Co0.67Zn0.83(btc)(H2O)6] (1) was prepared and characterized by elemental analysis, and FT-IR spectroscopy. The single crystal analysis was used for determination of its structure. The complex was used for the preparation of two inorganic precursors [Co0.67Zn0.83(btc)(H2O)6]/SiO2 and [Co0.67Zn0.83(btc)(H2O)6]/Al2O3, which were thermally decomposed to obtain new Co-Zn alloy catalysts for Fischer-Tropsch synthesis. The same catalysts were prepared by the conventional impregnation method as reference catalysts. The catalysts were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and BET specific surface area, and their catalytic performances were studied in the temperature range 200–300 °C and P = 5 bar. The results show that the Co-Zn synthesized alloy catalysts have acceptable activity in the Fischer-Tropsch (FTS) synthesis and have better selectivity to desired products than reference catalysts. The difference between the Co-Zn alloy catalysts and the reference catalysts is mainly caused by their different particle size.
