Pd-MoO3/TiO2催化糠醛氢解制备1,5-戊二醇
Hydrolysis of Furfural to Form 1,5-Pentadiol over Pd-MoO3/TiO2 Catalyst
【摘要】 开发生物基平台化合物糠醛向1,5-戊二醇转化的绿色合成路线是减少人们对化石燃料依赖的有效途径。本工作设计制备了Pd-MoO3/TiO2双功能催化剂,通过N2物理吸脱附,X射线光电子能谱(XPS),透射电镜(TEM)对其进行表征分析。对催化剂活性组分及载体进行筛选,优选出了Mo/Pd物质的量之比为1.5的催化剂,并对糠醛氢解反应路径进行了探究。实验结果表明,在150℃和H2压力为3MPa的条件下,糠醛在2 h内可以完全转化,1,5-戊二醇的收率可以达到56%,催化剂重复使用5次活性无明显下降,稳定性良好。
【Abstract】 Developing a green synthetic route for the conversion of biobased platform compound furfural to 1,5-pentadiol is an effective way to reduce our dependence on fossil fuels. In this paper, Pd-MoO3/TiO2 bifunctional catalyst was designed, prepared, and characterized by N2 physical adsorption and desorption,X-ray photoelectron spectroscopy(XPS) and transmission electron microscope(TEM). The active components and support of the catalyst were screened, the catalyst with the Mo/Pd atomic number ratio of 1.5 was selected, and the hydrogen hydrolysis reaction path of furfural was explored. The results showed that the furfural could be completely transformed within 2 h under the condition of 150 ℃ and H2 pressure of 3 MPa. The yield of 1,5-pentadiol could reach 56%. The activity of the catalyst had no obvious decrease after repeated use for 5 times.
