| 英文摘要 | fischer-tropsch synthesis (fts) is an important catalytic process for liquid fuel generation, which converts coal/shale gas/biomass-derived syngas (a mixture of co and h-2) to oil. while fts is thermodynamically favored at low temperature, it is desirable to develop a new catalytic system that could allow working at a relatively low reaction temperature. in this article, we present a one-step hydrogenation-reduction route for the synthesis of pt-co nanoparticles (nps) (nps) which were found to be excellent catalysts for aqueous-phase fts at 433 k. coupling with atomic-resolution scanning transmission electron microscopy (stem) and theoretical calculations, the outstanding activity is rationalized by the formation of co overlayer structures on pt nps or pt-co alloy nps. the improved energetics and kinetics from the change of the transition states imposed by the lattice mismatch between the two metals are concluded to be the key factors responsible for the dramatically improved fts performance. |
