| 英文摘要 | Fischer-Tropsch (F-T) synthesis at low temperature has attracted a lot of research attention due to its thermodynamically favorable nature at low temperature. Herein, we report a highly efficient solid nanoreactor for low temperature liquid-phase F-T synthesis. The solid nanoreactor was fabricated by encapsulation of Ru-PVP nanowires in ethane-silica hollow nanospheres via a one-pot co-condensation method. Under similar reaction conditions, the solid nanoreactor shows higher activity (activity: 6.35 versus 5.96 mol(CO) mol(Ru)(-1) h(-1)) and selectivity towards oxygenate products (41.3 versus 21.6%) than free Ru-PVP in aqueous F-T synthesis. The high activity and selectivity of the encapsulated Ru-PVP is mainly attributed to the low PVP/Ru ratio and the unique yolk-shell nanostructure in increasing the degree of exposure of the active sites. It was also observed that the selectivity towards C5-12 products could be increased to 63.8% in a water/cyclohexane biphasic system. Encapsulation not only gave rise to the quasi-homogeneous Ru-PVP with facile recycling ability, but also enhanced its activity and selectivity towards oxygenates. |
