The results show that MoO 3 and [Mo 7O 24 ] 6- may be reconstructed to [Mo 6O 19 ] 2- under the reaction conditions. The structure change only occurred on the catalyst surface, and thus [Mo 6O 19 ] 2- may be an active dynamic surface structure responsible for the better catalytic performance of selective oxidation of propane.展开更多
