Production of chemicals and fuels from renewable cellulosicbiomass is important for the creation of a sustainable society,and it critically relies on the development of new and efficienttransformation routes starting from cellulose. Here, a chemocatalytic conversion route from cellulosic biomass to methyl glycolate (MG), ethylene glycol (EG), and ethanol (EtOH) is reported. By using a tungsten-based catalyst, cellulose is convertedinto MG with a yield as high as 57.7 C% in a one-pot reactionin methanol at 240oC and 1 MPa O2, and the obtained MG canbe easily separated by distillation. Afterwards, it can be nearlyquantitatively converted to EG at 200oC and to EtOH at 280oCwith a selectivity of 50% through hydrogenation over a Cu/SiO2 catalyst. By this approach, the fine chemical MG, the bulkchemical EG, and the fuel additive EtOH can all be efficientlyproduced from renewable cellulosic materials, thus providinga new pathway towards mitigating the dependence on fossilresources.
