Magnetic Fe3O4-12 nanoparticles, an easily separable heterogeneous catalyst, exhibits high catalytic performance in the catalytic transfer hydrogenation (CTH) reaction of biomass-derived furfural (FAL) to furfuryl alcohol (FOL) with 2-propanol (2-PrOH) as the hydrogen source (90.1 % FOL yield at 160 °C for 5 h). Comparing Fe3O4 nanoparticles with different particle sizes found that the smaller the nanoparticles, the larger the BET surface area, pore volume and pore diameter, resulting in more acid-base active sites through BET, SEM, TEM, NH3-/CO2-TPD and other characterizations. Moreover, a scaled-up CTH experiment of FAL and a stepwise reaction from xylose to FOL verified that the catalytic system has great industrial application prospects. A feasible flowchart of the chemical process from xylose to FOL was designed, which can realize the regeneration of biomass resources (xylose derived from corncob), the reuse and recycling of catalysts and solvents, and minimize the amount of solvents and pollutant emissions.

磁性Fe 3 O 4纳米粒子作为易于分离的催化剂,可有效地将生物质衍生的糠醛催化转移催化氢化成糠醇

磁性Fe 3 O 4 -12纳米粒子是一种易于分离的非均相催化剂,在生物质衍生的糠醛(FAL)与2-丙醇(2-PrOH)转化为糠醇(FOL)的催化转移氢化(CTH)反应中表现出较高的催化性能。 )作为氢源(在160°C下加热5小时,FOL产率为90.1%)。比较具有不同粒径的Fe 3 O 4纳米粒子发现,纳米粒子越小,BET表面积,孔体积和孔径越大,通过BET,SEM,TEM,NH 3- / CO产生更多的酸碱活性中心2-TPD和其他特征。此外,FAL的大规模CTH实验以及从木糖到FOL的逐步反应证明了该催化体系具有广阔的工业应用前景。设计了从木糖到FOL的化学过程的可行流程图,该流程图可实现生物质资源(玉米芯衍生的木糖)的再生,催化剂和溶剂的再利用和再循环,并最大限度地减少溶剂和污染物的排放。
