Postsynthetic acid modification of amino-tagged metal-organic frameworks:Structure-function relationship for catalytic 5-hydroxymethylfurfural synthesis
文献摘要：
Developing an efficient and selective catalyst for the dehydration of fructose to 5-hydroxymethylfurfural(HMF)is significant for biomass conversion.Herein,a metal-organic framework(MOF)with acidity and strong hydrophobicity is first reported by the condensation of amino-tagged MOFs with mercapto car-boxylic acids and subsequent oxidation.The hydrophobic acidic MOFs possess acid densities ranging from 0.2-1.0 mmol·g-1,H2O contact angles of 114°-125°,and specific surface areas above 260 m2·g-1.Compared to the methyl sulfo-functionalized MOF,the benzene sulfo-functionalized MOF with a strong hydrophobicity shows much higher activity and selectivity for the conversion of fructose to 5-hydroxymethylfurfural.In particular,2.99％(mass)UiO-PhSO3H shows the best catalytic perfor-mance with a 90.4％HMF yield due to its suitable hydrophobicity and abundant acidic sites.Moreover,the catalyst shows great stability after recycling for 5 runs.This work provides an interesting design strat-egy for the preparation of hydrophobic acidic MOFs and shows the powerful synergistic effect of acidity and hydrophobicity.
