Abstract: Sulfur-doped carbon precursor are prepared by co-carbonization of cellulose and sulfur,which contain various forms of sulfur such as thiophene,sulfoxide,disulfide and so on.Then the precursor is oxidized under hydrogen peroxide-glacial acetic acid system to prepare carbon-based solid acid catalyst.This kind of catalyst contains sulfonic acid group,adds sulfone group and retains previous sulfur present form in the precursor.It is applied to catalyze the hydrolysis of cellulose,and its catalytic performance is evaluated by taking the yield of reducing sugar as index.Its optimal hydrolysis conditions and reusability are investigated.
