Synthesis of furfural from sugarcane bagasse by hydrolysis method using magnetic sulfonated graphene oxide catalyst

Abstract

Furfural, an important compound applied in many areas, could be synthesized from biomass which is inexpensive and abundant. In this study, magnetic sulfonated graphene oxide (Fe3O4/SGO) was synthesized and used as a catalyst for producing furfural from sugarcane bagasse by co-precipitation method. The characteristics of the catalyst material were investigated by Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, Raman spectroscopy, Brunauer-Emmett-Teller specific surface area, and the vibrating-sample magnetometer. The results showed that Fe3O4/SGO was successfully synthesized with a specific surface area of 121.8 m 2 /g. The empirical data indicated that under the condition of 190 o C, 90 mins of reaction, the furfural synthesis efficiency could reach 14.07 %. According to the results, Fe3O4/SGO is highly promising for furfural production from biomass.

Binary TiO2/reduced graphene oxide nanocomposite for improving methylene blue photodegradation

“…Raman spectra of rGO and TiO2/rGO materials were shown in figure 1c. The D band expressed characteristic of sp 3 hybridized carbon the disorder band associated with structural defects in graphene while the G band reveals the in-plane vibration of sp 2 bonded carbon regions, [14] which were briefly reported in table 1. The grafting of TiO2 in TiO2/rGO shown no considerable change in the D and G band and the enhanced intensity due to the presence of the dopants represents the impressive photocatalytic properties of the nanocomposite.…”
