| 英文摘要 | the selective oxidation of propylene with o-2 to propylene oxide and acrolein is of great interest and importance. we report the crystal-plane-controlled selectivity of uniform capping-ligand-free cu2o octahedra, cubes, and rhombic dodecahedra in catalyzing propylene oxidation with o-2: cu2o octahedra exposing {111} crystal planes are most selective for acrolein; cu2o cubes exposing {100} crystal planes are most selective for co2; cu2o rhombic dodecahedra exposing {110} crystal planes are most selective for propylene oxide. one-coordinated cu on cu2o(111), three-coordinated o on cu2o(110), and two-coordinated o on cu2o(100) were identified as the catalytically active sites for the production of acrolein, propylene oxide, and co2, respectively. these results reveal that crystal-plane engineering of oxide catalysts could be a useful strategy for developing selective catalysts and for gaining fundamental understanding of complex heterogeneous catalytic reactions at the molecular level. |
