Abstract
AbstractThe selective hydrogenation of furfural (FFA) to furfuryl alcohol (FA) is regarded as attractive transformation to achieve the sustainable synthesis of value‐added chemicals from biomass resources. However, the conventional supported catalysts are significantly restricted by their narrow pore size, ununiform dispersion and easy leaching or aggregation of catalytic sites. Herein, we designed hollow UiO‐66‐NH2 as the support to encapsulate Pd nanoparticles (Pd@H‐UiO‐66‐NH2) to achieve the highly active and selective conversion of FFA to FA. Benefiting from the void‐confinement effect and substrate enrichment of hollow structure, as well as the surface wrinkles, the as‐prepared catalyst Pd@H‐UiO‐66‐NH2 exhibited 96.8 % conversion of FFA with satisfactory selectivity reaching up to 92.4 % at 80 °C, 0.5 MPa H2 in isopropanol solvent within 6 h. More importantly, as‐prepared Pd@H‐UiO‐66‐NH2 catalyst exhibited excellent long‐term stability, as well as good universality toward a series of hydrogenation of unsaturated hydrocarbons.
