中文摘要	Increasing concerns about global warming and diminishing fossil fuel reserves have stimulated much effort to use (ligno)cellulose as an alternative to petroleum for the production of fuels and chemicals. The dissolution of (ligno)cellulose in ILs resulted in a full release of all the functional groups and bonds from the well-organized strong hydrogen bonding matrix, which have paved an environment-friendly and homogenous manner to use (ligno)cellulose.[1] Our previous works have demostrated that mineral acids (e.g. HCl, H2SO4) are effiecient catalysts for the hydrolysis of cellulose and lignocellulose in ILs, and the TRS yields were up to 66%, 74%, 81% and 68% for hydrolysis of corn stalk, rice straw, pine wood and bagasse, respectively; CrCl3 can promoted the production of HMF in ca. 60% and 90% isolated yields from cellulose and glucose, respectively, in ILs under microwave irradiation.[2] Recently, novel “greener’ Lewis acids, and solid acids have been screened and developed in our laborary for the catalytic conversion of carbohydrates. For example, GeCl4 is a very efficient catalyst for the dehydration of carbohydrates (e.g. Fructose, glucose, cellulose) into 5-hydroxymethylfurfural, with good yields ranging from 30% to 92% under mild conditions. Especially, a HMF yield of 92% was achieved in 5 mins in the case of fructose. Lignosulfuric acid is a by-product of industrial pulp paper making process, and we demostrated that it is a good solid catalyst for the conversion of fructose into HMF with a 90% yield in ILs.[3] In a word, novel Lewis acids and solid acids have been sreened and deveoped for the conversion of carbohydrates into valuable chemicals and biofuels. The application of ‘greener’ catalysts in combination of using ionic liquids as solvents for biomass conversion will lead to a more sustainable and efficient biorefinery.
