A Ag–Pd alloy supported on an amine-functionalized UiO-66 as an efficient synergetic catalyst for the dehydrogenation of formic acid at room temperature

Abstract

Highly dispersed Ag–Pd alloys deposited on an amine-functionalized UiO-66(NH₂–UiO-66) have been successfully prepared via a pre-coordination method. The as-synthesized AgPd@NH₂–UiO-66 catalyst exhibited 100% H₂ selectivity and a high catalytic activity (TOF = 103 h⁻¹) toward the dehydrogenation of formic acid at room temperature without any additives, which is among the highest values ever reported. Our study further reveals that the synergetic effect between the Ag–Pd alloy and NH₂–UiO-66 support play a key role for the efficient catalytic dehydrogenation of formic acid.
