摘要

The selective hydrogenolysis of C-O bond in furfural and its derivatives provides a sustainable route for transforming biomass-derived feedstocks into valued chemicals.Currently,the development of efficient catalysts which can effectively cleavage C-O bond under mild conditions remains a critical challenge.The present work reports Pt catalysts supported on multi-walled carbon nanotubes(MWNT)which are active in 2-methylfuran(2-MF)hydrogenolysis to form pentanols in liquid phase under mild conditions.The impact of various catalyst supports,active metals and reaction conditions in terms of metal loadings,solvent,time,pressure,etc.,were explored.The 5 wt％Pt/MWNT catalyst demonstrated an excellent activity and selectivity with 100％2-MF conversion and 53％pentanols(POLs)yield under 1 MPa H2 at an exceptional low temperature of 25℃.The reaction mechanism was studied combing both the reactivity tests and characterization results,and it is found that the better catalytic performances of Pt/MWNT were correlated clo-sely to the size of Pt nanoparticles and their interactions with the underlying MWNT support.Accordingly,a reaction pathway involving the adsorption of 2-MF parallel to the Pt nanoparticles and its subsequently selective C-O hydrogenolysis was proposed.This work showcases a promising catalyst for room-temperature biofuel produc-tion.
