| 英文摘要 | surface fe ensembles, surface alloyed fe atoms, and subsurface fe species have been identified at pt surfaces on the basis of studies in fe-pt(111) model systems and supported pt-fe nanoparticles (nps). the surface fe ensemble changes to ferrous oxide and forms a highly active and stable "feo-on-pt" structure in preferential oxidation of co in the presence of h-2 (prox), which, however, gets fully oxidized in co oxidation in the absence of h-2 (coox) and becomes inactive in the reaction. the surface alloyed fe remains stable under the h-2-rich and o-2-rich reaction conditions, which are active for both prox and coox reactions. accordingly, highly efficient pt-fe catalysts for the prox and coox reactions can be prepared via mild reduction and/or acid leaching. |
