| 英文摘要 | au/gamma-fe2o3 and au/alpha-fe2o3 catalysts with identical size of au nanoparticles, chemical state of au species, and amount of surface ow group were prepared. the au/gamma-fe2o3 catalyst exhibited exceptionally high activity, regardless of the heat treatments. the cotpr, sequential pulse reaction, and in situ raman spectra demonstrate that the much higher activity of au/gamma-fe2o3 originated from its higher redox property at low temperature. systematic study shows that this higher-redox-property-based higher activity could be extended to gamma-fe2o3-supported pt-group metals and to other reactions that follow mars-van krevelen mechanism. this finding may provide a new avenue for catalyst improvement or development by choosing the suitable crystal phase of the oxide support. |
