| 제목 | Hyperactive Fe5C2 Supported on N-doped steam activated rGO/CNT Hybrids for FTS |
| 초록 | The Fe5C2@NsrGO/CNT architecture, consisting of activated iron carbide nanoparticles on N-doped srGO sites with CNT branches, could be prepared via a simple microwave irradiation and CO activation process. The hybridization of CNT with graphene has been researched due to large specific surface area, fast mass transfer and mechanical∙chemical stability. In addition, the performance has been further improved by nitrogen doping because N-doped can play a vital role in changing in the electron density state and boning configuration. The unique structure showed very high performance for the HT-FTS reaction under a high GHSV of 210 NL•gcat-1 h-1 (FTY = 4.4 x 10-3molCO gFe-1 s-1, CO conversion = 80.5%, total hydrocarbon productivity = 49.2 x 10-3 gHC gFe-1 s-1). The high catalytic performance was attributed to the hierarchical structure of CNT-branched s-rGO with high surface area and threedimensionally interconnected pores, apt for fast mass transport, and N-doped sites enhancing the catalytic activity. It is anticipated that this approach may be extended to the preparation of other metal or metal carbide@NsrGO/CNT frameworks as productive catalysts. |
