采用溶胶固定化技术制备了一系列负载型钯催化剂，在温和条件下研究了生物醛的选择性加氢反应。采用氧化铝和二氧化钛作为载体的催化剂对四氢糠醇的选择性更强。考察了1.19% Pd/TiO2在不同反应条件下的催化活性，发现以2-丙醇为溶剂时，对四氢呋喃醇的选择性较高，反应温度升高，四氢呋喃醇的收率降低。Pt的加入提高了钯催化剂的性能，四氢糠醇的收率达到95%。使用一系列技术对催化剂进行了表征，将Pt添加到Pd的协同效应是由于电子促进效应。
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.
