英文摘要	a series of sulfonic acid-functionalized metal-organic frameworks (mof-so3h) were prepared by postsynthetic modification (psm) of the organic linkers within the mof with chlorosulfonic acid. the obtained mof-so3h, including sulfonic acid-functionalized mil-101(cr) [mil-101(cr)-so3h], uio-66(zr) [uio-66(zr)-so3h], and mil-53(al) [mil-53(al)-so3h], have been systematically studied as solid acids in fructose transformation to 5-hydroxymethylfurfural (hmf). with mil-101(cr)-so3h as catalyst, a hmf yield of 90% with a full fructose conversion was obtained at 120 degrees c for 60 min in dmso. the concentration of -so3h in mof-so3h as well as the contribution of bronsted acidity of mof-so3h parallels its -so3h grafting rate. under a lower -so3h grafting level, a good linear correlation between catalytic activity, in terms of turnover frequency, and sulfonic acid-site density of mof-so3h was found. moreover, the sulfonic acid groups, which function as the catalytic sites, are equivalent in all mof-so3h for fructose-to-hmf transformation, regardless of precursor mofs. both conversions of fructose and selectivities towards hmf increase with the sulfonic acid-site density of mof-so3h at an initial stage of fructose-to-hmf transformation. kinetics studies reveal that the mil-101(cr)-so3h promoted fructose-to-hmf transformation may follow pseudo-first-order kinetics with observed activation energy of 55 kj mol(-1) under the investigated conditions. moreover, mil-101(cr)-so3h behaves as a heterogeneous catalyst and can be easily recovered and reused. the research highlights a good prospect for catalytic application of mof-derived solid acid catalysts for biomass carbohydrate valorization.
