Furfuryl alcohol, as a representative derivative of platform chemical- furfural, could transform into highly value-added diol by hydrogenolysis of furan-ring. The steric hindrance of hydroxymethyl inhibits the selectively hydrogenolysis of furfuryl alcohol to form 1,5-pentanediol. Aiming at solving the low activity and selectivity of existing metal-metal oxide catalytic system, a M-quasi-MOF model catalyst will be designed to replace the existing one. Based on the new model catalyst, the improved technical solution could be proposed assisted by experiment and DFT calculation, to realize the selective transformation from furfuryl alcohol to 1,5-pentanediol, and avoiding the preferential formation of 1,2-pentanediol occurred on traditional catalysts. By constructing M-quasi-MOF model catalyst, the anchor of furfuryl alcohol and nano-metal clusters by structural defect and coordination unsaturated site on different Al-O clusters will be investigated, and the synergistic mechanism of surface acid-site and metal clusters on catalyzing furfuryl alcohol to 1,5-pentanediol will be acquire. Through using various characterization method, such as in-situ DFTIR spectra, the catalytic reaction mechanism, accompanied with the reactant conversion process and intermediates formation will be revealed. Exploring the relevance between acid-sites on catalysts surface / interface and selective formation of 1,5-pentanediol, could be helpful for developing the controllable strategy on enhancing 1,5-pentanediol production, and laying the foundation for the industrial application of furfuryl alcohol hydrogenolysis catalysts to produce 1,5-pentanediol.
