The development of an environmentally friendly synthesized biomass-derived catalyst for the conversion of hemicellulose to platform chemicals has attracted worthwhile attention. In this work, an acidic carbon-based catalyst (C-SGO) with a structure resembling sulfonated graphene oxide is synthesized from corncob-extracted cellulose by bleaching, alkalization, carbonization, and sulfonation processes. Characteristics of the as-synthesized C-SGO were investigated using Fourier-transform infrared spectroscopy, X-ray diffraction spectroscopy (XRD), Raman spectroscopy, energy dispersive spectroscopy, thermal gravimetric analysis, Brunauer–Emmett–Teller, and scanning electron microscopy (SEM). Raman spectrum of C-SGO spectroscopy indicated the existence of D and G bands at 1338.72 and 1593.41 cm−1, respectively. SEM images of C-SGO showed sheet-like structures with folds and wrinklier after the sulfonation process, confirming the structural similarity of the synthesized material to sulfonated graphene oxide sheets. The synthesized C-SGO catalysts were applied for the conversion of hemicellulose from corncob to furfural. The synergistic effect of C-SGO and the concentration of NaCl 0.2 mol/L in the furfural synthesis reaction achieved a yield of 40.03% at a temperature of 200 °C, time of 90 min, and 100 mg of the catalyst amount, showing the potential of using seawater or wastewater containing NaCl as a low-cost solvent. Moreover, the catalyst also demonstrated reusability after 5 cycles, showing that C-SGO can be used as a heterogeneous catalyst suitable for furfural synthesis. [ABSTRACT FROM AUTHOR] |
