The conversion of cellulose into valuable chemicals has attracted a great deal of interest. In this study, heterogeneous and homogeneous systems in the conversion of bagasse cellulose into the total reducing sugars were investigated. In the heterogeneous system, the effects of several critical factors including types and concentrations of ionic liquid, temperature, and time were all investigated for cellulosic conversion. Parameters considered included temperature, dosage of catalyst, and water in the homogeneous system. It was found that the hydrolysis capacity for cellulose in homogeneous system was better than that in heterogeneous system. In addition, the structure and physicochemical properties of the treated cellulose were characterized by Fourier transform infrared spectroscopy, thermogravimetry, and scanning electron microscopy, and then compared with the native fibers. © 2015 Wiley Periodicals, Inc.
