采用水热-氢气还原法合成了镁铝复合金属氧化物负载 Ru 纳米颗粒催化剂,利用 X 射线衍射(X-ray diffraction,XRD)、扫描电镜(scanning electron microscope,SEM)、透射电镜(transmission electron microscope,TEM)、N2 物理吸附、CO2-程序升温脱附(CO2-temperature programmed desorption,CO2-TPD)、电感耦合等离子体发射光谱(inductively coupled plasma-optical emission spectroscopy,ICP-OES)等表征手段对催化剂进行结构、形貌和组成分析。结果表明,镁铝物质的量之比 n(Mg):n(Al)=5:1 的催化剂载体具有最强的碱性(142.81 mmol·g-1)和较大的比表面积(97.0 m2·g-1),有利于负载高分散的 Ru 纳米颗粒。在最佳反应条件(120 ℃、2 MPa O2、5 h)下,负载量为 2.0% 的 RO-5 催化剂能够高效催化 5-羟甲基糠醛(5-hydroxymethylfurfural,HMF)氧化制备 2,5-呋喃二 甲酸(2,5-furandicarboxylic acid,FDCA),HMF 转化率和 FDCA 产率分别达到 100.0% 和 99.0%。条件优化实验进一步证实,HMF 催化氧化的反应路径为生成 2,5-呋喃二甲醛(2,5-diformylfuran,DFF)和 5-甲酰基-2-呋喃甲酸(5-formyl-2-furancarboxylic acid, FFCA)中间产物的过程。

Ru nanoparticles supported on Mg-Al mixed metal oxide catalysts have been prepared via the hydrothermal-reduction method. The structure, morphology and composition of the catalysts have been systematically analyzed using X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), N2 physisorption, CO2-temperature programmed desorption（CO2-TPD) and inductively coupled plasma-optical emission spectroscopy (ICP-OES). The characterization results show that the highly dispersed Ru nanoparticles benefit from the strongest alkalinity (142.81 mmol·g-1 and the competitive specific surface area (97.0 m2·g-1 of mixed metal oxides with n(Mg):n(Al)=5:1. The RO-5 catalyst with Ru loading of 2.0% can efficiently catalyze aerobic oxidation of 5-hydroxymethylfurfural (HMF), obtaining 100.0% HMF conversion and 99.0% 2,5-furandicarboxylic acid (FDCA) yield under the optimal reaction condition (120 ℃ , 2 MPa O2, 5 h). According to the optimizing results, the reaction pathway for the conversion of HMF to FDCA is further confirmed for the formation of 2,5-diformylfuran,(DFF) and 5-formyl-2-furancarboxylic acid (FFCA) intermediates.
