该报告表明，使用负载的Pd纳米颗粒可以选择性地由糠醛加氢制备糠醇。糠醇广泛用作溶剂和精细化学品合成的中间体。这里，通过使用硝酸钯的湿浸渍，简单地制造了负载在介孔SiO2（Pd/SiO2）上的各种Pd纳米颗粒。通过X射线衍射、能谱分析、X射线衍射、N2吸附-脱附等温线和透射电子显微镜研究了Pd/SiO2纳米粒子的物理性质。结果表明，具有小尺寸的Pd纳米粒子的高分散性。在温和条件下，Pd纳米粒子对糠醛加氢制糠醇具有很高的催化活性，选择性为76%。总的来说，所开发的催化剂可以用于从生物质生产化学品。
This report shows that furfuryl alcohol can be selectively produced from the hydrogenation of furfural using supported Pd nanoparticles. Furfuryl alcohol is widely used as solvent and chemical intermediate for the synthesis of fine chemicals. Here, various Pd nanoparticles supported on mesoporous SiO2(Pd/SiO2) were simply fabricated by a wet impregnation using palladium nitrate. Physical properties of Pd/SiO2nanoparticles were studied by X-ray diffraction, energy-dispersive, X-ray analysis, N2adsorption and desorption isotherms and transmission electron microscopy. Results show a high dispersion of Pd nanoparticles with small size. Pd nanoparticles catalyzed very efficiently the hydrogenation of furfural to furfuryl alcohol with 76 % selectivity under mild conditions. Overall, the catalyst developed could find applications for the production of chemicals from biomass.
