Herein, a series of Pd nanoparticles supported on Cu-MOFs (Cu3(BTC)2, FeCu-DMC) with pure Lewis acidity are synthesized for hydrogenative ring-rearrangement reaction of furanic aldehydes (furfural, 5-hydroxymethyl furfural) to Cyclopentanone (cas 120-92-3) compounds (cyclopentanone, 3-hydroxymethyl cyclopentanone). For both furfural and 5-hydroxymethyl furfural, the hydrogenation rate catalyzed by the Pd/Cu-BTC is six times faster than Pd/FeCu-DMC, due to the higher dispersion of Pd nanoparticles. Meanwhile, Pd/Cu-BTC with strong acidity for the selectivity of cyclopentanone compounds is more than 90%, while as for Pd/FeCu-DMC, furanic alcohols (furfuryl alcohol, 2,5-bis(hydroxymethyl)furan) are only actually be obtained because weak acidity cannot incur subsequent hydrolysis reaction.
