Cu-embedded porous Al2O3 bifunctional catalyst derived from metal-organic framework for syngas-to-dimethyl ether
文献摘要：
Dimethyl ether(DME),as a promising alternative to diesel fuel and liquefied petroleum gas,has attracted considerable attention in catalysis domain.The catalytic direct synthesis of DME from syngas is an up-and-coming route but remains a challenge.In this work,we firstly prepared a Cu-embedded porous A12O3 bifunctional catalyst(Cu@Al2O3-dp)by filling Cu-1,3,5-benzenetricarboxylate metal-organic framework(Cu-BTC MOF)with Al(OH)3 followed by a two-step calcination process(400℃for 4h and 600℃for 1 h),exhibiting excellent catalytic performance for direct synthesis of DME from syngas.Cu@Al2O3-dp catalyst demonstrates much higher CO conversion(25.7％vs.15.4％)and extremely higher DME selec-tivity(90.4％vs.63.9％)with the increased catalytic stability compared to the supported Cu catalyst on MOF-derived porous Al2O3(Cu/Al2O3)prepared by incipient wetness impregnation method,ascribed to the unique embedding-type structure,promoted Cu dispersion and stronger metal-support interaction.This work not only provides an efficient syngas-to-DME catalyst,but also paves a new way for designing highly-efficient core-shell bifunctional catalysts for diverse consecutive reactions.
