The selective hydrogenation of bio-derived furfural was investigated under mild conditions using a series of supported palladium catalysts prepared by a sol-immobilisation technique. Catalysts using alumina and titania supports were more selective towards tetrahydrofurfuryl alcohol. The catalytic activity of 1.19% Pd/TiO₂ was evaluated under different reaction conditions and higher selectivity towards tetrahydrofurfuryl alcohol was observed when using 2-propanol as a solvent, and the yield of tetrahydrofurfuryl alcohol decreased as reaction temperature increased. The performance of the Pd catalyst was enhanced by the addition of Pt and a 95% yield of tetrahydrofurfuryl alcohol was achieved. The catalysts were characterised using a range of techniques, and the synergistic effect of adding Pt to Pd was due to an electronic promotional effect.

溶胶固定化负载型钯纳米粒子催化剂上糠醛的选择性加氢：催化剂载体和反应条件的影响†

在温和的条件下，使用一系列通过溶胶固定技术制备的负载型钯催化剂，对生物衍生糠醛的选择性加氢进行了研究。使用氧化铝和二氧化钛载体的催化剂对四氢糠醇的选择性更高。1.19％Pd / TiO ₂的催化活性在不同的反应条件下对H 2 O 3进行评价，并且当以2-丙醇为溶剂时观察到对四氢糠醇的更高的选择性，并且四氢糠醇的产率随着反应温度的升高而降低。通过添加Pt提高了Pd催化剂的性能，并获得了95％的四氢糠醇产率。使用多种技术对催化剂进行了表征，并且将Pt添加到Pd中的协同作用归因于电子促进作用。
