Furfural is a promising platform substance derived from biomass and widely applied in various industrial sectors. In this current work, two main components in biomass, namely cellulose and hemicellulose, were remarkably exploited for carbonization and sulfonation processes, in turn being respectively the synthesis of sulfonated graphene oxide-like (CB − SGO) catalyst and then utilization in the furfural-derived biomass conversion. The catalyst was characteristically analyzed by modern analytical methods, the results reveal that CB − SGO catalysts were shaped as arbitrarily stacked sheets similar to the structure and morphology of graphene oxide and contained various oxygen functional groups. In addition, CB − SGO plays the role of a catalyst for the conversion of biomass-derived hemicellulose into furfural with a notable efficiency of 25.3% upon sulfonated CB − GO catalyst with H2SO4 2 M. The highest furfural efficiency (66.86%) of the CB − SGO 2 M was also affirmed with the optimal conditions at 190 °C, 60 min, a 5 mg catalyst system within a solvent mixture of water and ɣ-valerolactone (volume ratio of 4:1). Conclusively, this study proposes an alternative solution for biomass to synthesize catalysts efficiently converting hemicellulose into furfural. [ABSTRACT FROM AUTHOR] |
