摘      要：Abstract A detailed study on the synergetic effect of TeMo 5 O 16 and MoO 3 phases in the MoTeO x catalysts for the partial oxidation of propylene to acrolein has been reported in this work. It was found that both propylene conversion and acrolein selectivity increased with the addition of MoO 3 to TeMo 5 O 16 . Based on the results of N 2 adsorption-desorption, XRD, XPS, in-situ XRD, O 2 -TPO, and 2-propanol decomposition reaction, the higher catalytic performance and synergetic effect could be attributed to the enhancement of acidity and the oxygen transfer from TeMo 5 O 16 to MoO 3 phase.
