Effects of impregnation strategy on structure and performance of bimetallic CoFe/AC catalysts for higher alcohols synthesis from syngas

Iron-based catalysts encapsulated by nitrogen-doped graphitic carbon for selective synthesis of liquid fuels through the Fischer-Tropsch process

“…The peaks below 500 °C were attributed to the following consecutive reduction steps: Fe2O3 → Fe3O4 → FeO → Fe [35]. Meanwhile, the broad peak at 569 °C was assigned to methanation of the carbon shell in the presence of metallic Fe, which has also been observed by others [36]. In the case of FeC-900, the reduction peaks shifted to higher temperatures, indicating the hard reducibility of the iron phases.…”

Carbon-based catalysts for Fischer–Tropsch synthesis

“…78 The metal impregnation sequence plays an important role in the activity, selectivity, and product distributions of the Fe/AC catalysts. 89 The impregnation of Fe followed by Co on a 15Co-5Fe/AC catalyst was found to result in a more active catalyst than the reversed order of impregnation. The Co-Fe alloy was observed in bimetallic 15Co-5Fe/AC which exhibits high CO uptake and more cobalt active sites on the surface of the catalyst.…”

Recent Progress in CO Hydrogenation over Bimetallic Catalysts for Higher Alcohol Synthesis

“…Du et al [27] also studied the influence of impregnation strategy on the catalytic activity of activated carbon-supported cobalt and iron-based bimetallic catalysts for higher alcohol synthesis from syngas. The sequential impregnation, in which iron was impregnated first and copper second, exhibited better catalytic performance in comparison to co-impregnated catalysts.…”
