采用简单共沉淀法制备Ru/ co3o4催化剂,首次用于催化5-羟甲基糠醛(HMF)转化为2,5-二甲基呋喃(DMF),并表现出优异的催化性能。在较低的反应温度和H2pressure(130℃,0.7 MPa)条件下,DMF的产率达到93.4%。进一步的研究表明Ru负责氢化,而coox在羟基的氢解中起重要作用。此外,该催化剂还具有良好的可重复使用性,可重复使用5次而不损失活性。
Ru/Co3O4catalyst prepared by a simple coprecipitation method, was used to catalyze the conversion of 5-hydroxymethylfurfural (HMF) into 2,5-dimethylfuran (DMF) for the first time and exhibited excellent catalytic performance. 93.4% yield of DMF was achieved at relatively low reaction temperature and H2pressure (130 °C, 0.7 MPa). Further studies showed that Ru is responsible for hydrogenation, while CoOxspecies played important role in the hydrogenolysis of hydroxyl groups. Besides, this catalyst also displayed a good reusability and can be used for 5 times without loss of the activity.
