As　the　supplies　of　fossil　resources　are　inevitably　declining,　converting　lignocellulose　into　high　value-added　chemicals,　which　can　be　used　as　alternatives　to　industrial　raw　materials　or　energy　oil,　becomes　a　hotspot　of　current　research　and　has　broad　prospects　for　development.　In　this　paper,　the　type,　role　and　research　progress　of　catalysts　used　in　the　liquefaction　of　lignocellulose　were　reviewed　in　detail,　including　liquid　inorganic　acid　represented　by　concentrated　sulfuric　acid,　solid　inorganic　base　represented　by　NaOH,　organic　acid　represented　by　oxalic　acid,　salts　represented　by　AlCl3,　solid　heteropoly　acid　represented　by　Cl-/Fe2O3.　Meanwhile,　the　advantages　and　disadvantages　of　different　types　of　catalysts　were　discussed,　and　then　the　developing　prospects　of　catalyst　used　in　the　process　of　lignocellulose　liquefaction　were　forecasted.　©　2017,　Editorial　Board　of　Polymer　Materials　Science　&　Engineering.　All　right　reserved.
