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 and53%pentanols (POLs) yield under 1 MPa H;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 closely 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 production.
