外文摘要：The unique properties of metal oxide surfaces,crystal surfaces and defects play vital roles in biomass upgrading reactions.In this work,hierarchical porous bowl-shaped ZrO2(HB-ZrO2)with mixed crystal phase was designed and employed as the support for loading AuPd bimetal with different proportions to synthesize AuPd/HB-ZrO2 catalysts.The effects of surface chemistry,oxygen defects,bimetal interaction and metal-support interaction of AuPd/HB-ZrO2 on catalytic performance for the selective oxidation of 5-hydroxymethylfurfural(HMF)to 2,5-furandicarboxylic acid(FDCA)were systematically investigated.The Au2Pd1/HB-ZrO2 catalyst afforded a satisfactory FDCA yield of 99.9％from HMF oxidation using O2 as the oxidant in water,accompanied with an excellent FDCA productivity at 97.6 mmol g-1 h-1.This work offers fresh insights into rationally designing efficient catalysts with oxygen-rich defects for the catalytic upgrading of biomass platform chemicals.
