| 제목 | Active bimetallic compound of iron and cobalt metal inside functionalized CNT for CO2 Hydrogenation |
| 초록 | Global warming and energy problem comes from fossil fuel have accelerated diverse energy research, reforming, CO2 hydrogenation and F-T reaction (fischer-tropsch) to produce liquid product or light hydrocarbon. CO2 hydrogenation consists of RWGS (reverse water gas shift) and F-T reaction. 3mol of H2 and 1mol of CO2 are reacted with each other in proper reaction condition. In this work, we present cobalt, indicating any RWGS activity, and iron catalyst showed improved CO2 conversion and light hydrocarbon selectivity (C2-C4) compared to bare iron catalyst. Especially, by adding 1 percent of cobalt, iron loaded on inside of CNT has upper properties. Cobalt metal acted as promoter to help iron reduced and CO2 adsorption. Furthermore, to convert selectivity into higher hydrocarbon, potassium loaded on functionalized CNT with modified impregnation methods. |
