Abstract

Abstract : Installing sulfate and Pd in MOF-808 achieved glycerol conversion to 1, 2-PDO via selective hydrogenolysis. Abstract : Selective hydrogenolysis of glycerol to 1, 2-propanediol is one of the options for the chemical utilization of glycerol. In this work, we synthesized sulfate-functionalized metal–organic frameworks loading palladium nanoparticles, MOF-808-SO4 -Pd, as effective glycerol hydrogenolysis catalysts. The sulfate groups are responsible for the dehydration of glycerol. Subsequently, palladium nanoparticles hydrogenate the intermediates to 1, 2-propanediol. The synergistic reaction between acid sites and Pd gave 93.9% selectivity of 1, 2-propanediol with a reaction rate of 22.4 mmol gPd −1 h −1 . Our work highlights new opportunities in using acid-functionalized MOFs as novel supports for metal nanoparticle catalysts for dual site catalysis.
