A series of zirconium-based catalysts were prepared for the selective transfer hydrogenation of biomass-derived furfural (FFR) into furfuryl alcohol with lower alcohols as hydrogen sources. The sample structures were clearly characterized using various methods, such as X-ray powder diffraction, thermogravimetric analysis, scanning electron microscope, NH3-temperature-programmed desorption (TPD), CO2-TPD, and nitrogen physisorption. Excellent furfuryl alcohol yield of 98.9 mol % was achieved over Zr(OH)4 using 2-propanol as a hydrogen donor at 447 K. The poisoning experiments indicated that basic centers displayed pronounced effect for FFR transfer hydrogenation. Moderate monoclinic phase content in ZrO2-x enhanced the conversion rate and furfuryl alcohol selectivity, whereas acid-basic site density ratio had slight influence on FFR conversion. Besides, Zr(OH)4 revealed good performance and stability after being repeated four times. The possible mechanism for this transfer hydrogenation process over Zr(OH)4 catalyst with 2-propanol as the hydrogen source was proposed.

使用低级醇作为氢供体，在含Zr催化剂上将糠醛选择性转移加氢成糠醇。
制备了一系列锆基催化剂，以低级醇为氢源，将生物质衍生的糠醛（FFR）选择性转移加氢成糠醇。使用各种方法（例如X射线粉末衍射，热重分析，扫描电子显微镜，NH3温度程序解吸（TPD），CO2-TPD和氮物理吸附）清楚地表征了样品结构。使用2-丙醇作为氢供体，在447 K上，Zr（OH）4的糠醇收率为98.9 mol％。ZrO2-x中适度的单斜晶相含量提高了转化率和糠醇的选择性，而酸碱位密度比对FFR的转化影响很小。此外，Zr（OH）4重复四次后表现出良好的性能和稳定性。提出了在Zr（OH）4催化剂上以2-丙醇为氢源的转移加氢过程的可能机理。
