“…In this study, the GO synthesized from corncob cellulose can be further applied as a solid acid catalyst for converting hemicellulose to furfural. [20] Subsequently, 145.0 g of cellulose was mixed with 117.16 g of Fe(NO 3 ) 3 catalyst, followed by graphitization at 900 °C for 1 h to yield 40.00 g of Gi-Fe(NO 3 ) 3 . The sample of Gi-Fe(NO 3 ) 3 was further refluxed, specifically, 1.00 g Gi was dispersed into KMnO 4 solution containing 135.00 mL distilled water, 65.0 mL H 2 SO 4 5 M, and 5.00 g KMnO 4 .…”

“…[17] In addition, previous research also mentioned the synthesis of materials with a similar structure to GO to form Cel-MSGO, applied for converting hemicellulose to furfural, with the goal of converting corncob precursors into products with high value. [20] This study focuses on the exploitation of corncob, which is an abundant and affordable source of raw material, as a carbon source. This biomass material is separated from corn kernels either mechanically or manually in the corn production process, and for every 1 kg of corn collected, about 0.22 kg of cob is produced, possibly resulting in up to 203 million tons of cob annually owing to maize cultivation.…”

Recently, though graphene oxide (GO) has shown promising applications in many fields, there have not been many studies focusing on exploiting the source of synthetic precursors of GO. Herein, GO was synthesized from the cellulose of corncob by corncob alkalization, bleaching cellulose, pyrolysis, and improved Hummer's method. It was found that pyrolysis plays an important role in the graphitization of cellulose precursors with the catalyst Fe(NO3)3 to form Gi‐Fe(NO3)3. The GO material synthesized from Gi‐Fe(NO3)3 was characterized by advanced analytical methods. The X‐ray diffraction pattern of Gi‐Fe(NO3)3 shows the formation of a diffraction peak at the crystal plane (002), which is characteristic of the graphite material. The synthesized GO underwent a series of changes in material structure and morphology, which are confirmed via transmission electron microscopy images showing a plate‐like structure with folds represented by the dark line. This study demonstrates a sustainable approach that directly utilizes abundant biomass resources for the synthesis of GO material.

“…Biomass, recognized as the renewable organic carbon source, is increasingly being converted into high-value products as an alternative to fossil fuel consumption. 1 Biomass of agricultural residues is rich in carbohydrates, of which lignocellulose accounts for about 85−90% of dry weight. 2 The amorphous hemicellulose in lignocellulose can be hydrolyzed, generating monosaccharides such as xylose through breaking the glycosidic bonds with the help of the acid catalyst and then dehydrating to form furfural.…”

Catalytic transformation of agricultural residues to furfural is a potential source of income for those who have biomass residues to be disposed because furfural derivatives are platform molecules for the preparation of various chemicals, additives, and pharmaceutical precursors. In this work, a modified KIT-6 molecular sieve catalyst with dual acid sites of Lewis acid and Brønsted acid is prepared by grafting sulfonic acid groups on Sn 4+ -doped KIT-6. Characterizations are applied to reveal the generation of Lewis acid and Brønsted acid by the doped Sn 4+ and grafted sulfonic acid groups. The dual acid on the catalyst synergistically contributes to the satisfying catalytic transformation of xylose to furfural. In addition, the one-step and two-step transformations of agricultural residues to furfural and 5-hydroxymethylfurfural were studied. The prepared catalyst shows satisfying stability, and the reason for the slight decline of the catalytic performance was revealed.

“…Firstly, these processes yield only about 50% of the theoretical value and require long reaction times. 13 Secondly, challenges arise in wastewater management during the production process, leading to equipment corrosion and difficulties in FF separation. 14 Thirdly, substantial energy consumption is observed due to the use of steam as both the heat source and extractant.…”
