| 제목 | Apllication of ordered mesoporous Fe-Ni mixed metal oxides for water-gas shift reaction |
| 초록 | Water-gas shift (WGS) reaction is important to produce hydrogen-rich reformates for a fuel cell application and other hydrogen production process. An ordered mesoporous Fe-Ni mixed metal oxide was applied for a high temperature WGS reaction, which was prepared by using a nanocasting method with a hard template of KIT-6. The as-synthesized mesoporous FeNiOx showed a high catalytic activity and stability while preserving its original mesoporous structure with less aggregations of iron nanoparticles at an optimal Fe/Ni ratio of 0.25 even under reductive WGS reaction conditions. The strongly interacted Fe2O3 with NiO seem to be responsible for insignificant structural collapses by showing a HT-WGS activity, which were verified by TPR, TEM and XPS analyses. Key words: Water-gas shift (WGS) reaction; Ordered mesoporous FeNiOx; Structural stability; Nanocasting methods; KIT-6. |
