【摘要】An efficient heterogeneous catalyst, Pd@MIL-101(Cr)-NH2, is prepared through a direct pathway of anionic exchange followed by hydrogen reduction with amino-containing MIL-101 as the host ma-trix. The composite is thermally stable up to 350 ℃ and the Pd nanoparticles uniformly disperse on the matal organic framework (MOF) support, which are attributed to the presence of the amino groups in the frameworks of MIL-101(Cr)-NH2. The selective hydrogenation of biomass-based fur-fural to tetrahydrofurfuryl alcohol is investigated by using this multifunctional catalyst Pd@MIL-101(Cr)-NH2in water media. A complete hydrogenation of furfural is achieved at a low temperature of 40 ℃ with the selectivity of tetrahydrofurfuryl alcohol close to 100%. The amine-functionalized MOF improves the hydrogen bonding interactions between the intermediate furfuryl alcohol and the support, which is conducive for the further hydrogenation of furfuryl alco-hol to tetrahydrofurfuryl alcohol in good coordination with the metal sites.%随着资源枯竭和环境污染严重问题的凸显,生物质转化的研究越来越多,特别是生物质催化裂解制备生物燃料及高附加值的化学品.糠醛是一种半纤维素酸解的产物,
