| 1 | Efficient base-free oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid over copper-doped manganese oxide nanorods with tert-butanol as solvent显示文摘2,5-Furandicarboxylic acid(FDCA)is an important and renewable building block and can serve as an alternative to terephthalic acid in the production of biobased degradable plastic.In this study,Cu-doped MnO_(2) nanorods were prepared by a facile hydrothermal redox method and employed as catalysts for the selective oxidation of 5-hydroxymethylfurfural(HMF)to FDCA using tert-butyl hydroperoxide(TBHP)as an oxidant.The catalysts were characterized using X-ray diffraction analysis,Fourier transform infrared spectroscopy,thermo-gravimetric analysis,and transmission electron microscopy.The effects of oxidants,solvents,and reaction conditions on the oxidation of HMF were investigated,and a reaction mechanism was proposed.Experimental results demonstrated that 99.4% conversion of HMF and 96.3% selectivity of FDCA were obtained under suitable conditions,and tert-butanol was the most suitable solvent when TBHP was used as an oxidant.More importantly,the Cu-doped MnO_(2) catalyst can maintain durable catalytic activity after being recycled for more than ten times. | Feng Cheng Dongwen Guo Jinhua Lai Meihui Long Wenguang Zhao Xianxiang Liu Dulin Yin | 2021 | Frontiers of Chemical Science and Engineering2021，15，4： | 2 |
