A new hydrazone ligand, 4-methoxyacetophenone benzoyl hydrazone and its cobalt complex were synthesized and characterized using elemental analysis, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, 1 H NMR spectral data, and powder X-ray diffraction techniques. Moreover, the thermal gravimetric analysis and electrochemical (cyclic voltammetry) properties of the ligand and its complex were investigated. The catalytic ability of the Co-MABH complex as a new metal-organic catalyst in the Fischer-Tropsch reaction was investigated. The CO conversion under the operational conditions T = 100°C, P = 8 atm and ratio of H 2 /CO = 2 was found to be 50.21 %. The physicochemical characteristics of the catalyst were examined using scanning electron microscopy, and Brunauer-Emmett-Teller analysis at different operational stages.
