With the increasing demand for fossil energy and carbon resources, improving the efficiency of fossil resource utilization and exploring new ways of carbon resource utilization have become the key issues facing social development. Here, we successfully synthesized zirconium tannate(Zr-TA) from tannic acid(TA) and zirconium tetrachloride(ZrCl4) for catalytic transfer hydrogenation(CTH) of furfural(FF) to furfurfuryl alcohol(FA) with 100 % conversion of FF and 98.2 % yield of FA at 120 °C for 80 min. The physical properties of the catalysts and the optimum conditions for hydrogenation reaction were explored through different characterization techniques and experiments. In addition, the Zr-TA could be recycled eight times without significant loss of activity and possible reaction mechanism were proposed.

一种高稳定性的新颖鞣酸锆合成方法:对加氢催化剂结构的新见解

随着对化石能源和碳资源需求的增加,提高化石资源利用效率和探索碳资源利用新途径已成为社会发展面临的关键问题。在这里,我们成功地从单宁酸(TA)和四氯化锆(ZrCl 4)合成了鞣酸锆(Zr-TA),用于糠醛(FF)催化转移加氢(CTH)到糠醇(FA),FF和在120°C下搅拌80分钟,FA的产率为98.2%。通过不同的表征技术和实验,探索了催化剂的物理性质和最佳的加氢反应条件。此外,Zr-TA可以循环使用八次而不会显着降低活性,并提出了可能的反应机理。
