英文摘要	Anti-sintering platinum-based catalyst for propane dehydrogenation (PDH) is promising to avoid corrosive oxychlorination re-dispersion of sintered Pt during coke combustion. Herein, we report an anti sintering Pt/MgAl2O4 catalyst and optimizations on its activity for PDH with group IB metals (Cu, Ag and Au). Using a suite of characterizations including BET, H-2 chemisorption, XRD, STEM, CO-DRIFTS, XANES, XPS, TG/DTA, TPO, C3H6-TPD and TPSR of C3H6 with H-2, we reveal that Cu and Ag dilute the surface Pt atoms and donate electron to Pt while the case for Pt-Au is inverse. As a result, significant enhancements in propane conversion and propylene selectivity were obtained on the Pt-Cu/MgAl2O4 and Pt-Ag/MgAl2O4 catalysts. The Pt-Cu/MgAl2O4 exhibited excellent C3H6 yield and regeneration stability, presumably due to the formation of intermetallic compounds and little phase segregation during cyclic dehydrogenation-regeneration runs.
