“…Because of the recalcitrant property, it is difficult to efficiently extract the cellulose, in order to apply it. Hence, the lignocellulose biomass has also been refined into bioethanol and biodiesel by chemical or biological catalysis process [15][16][17], or been prepared into biomass based carbon materials for supercapacitor electrode [18,19]. A specific cellulose such as nanocrystal [20][21][22] or nanofibers cellulose hydrogels [23][24][25] has been applied for 3D printing to fabricate 3D structures.…”

AbstractCellulose is the most abundant natural polymer on earth, which has obtained increasing interest in the field of functional materials development for its renewable, high mechanical performance and environmental benign. In this study, the traditional processing method (wet spinning and film production) of cellulose-based materials was applied by using cellulose solution for 3D printing, which can directly build complex 3D patterns. Herein, a natural cellulose is dissolved in an effective mixed aqueous solution of dimethyl sulfoxide (DMSO) and tetrabutylammonium hydroxide (TBAH). The cellulose solution extrusion was controlled by a modified fused deposition modeling (FDM) 3D printer. During the controlled extrusion 3D printing process, the viscous cellulose solution will gelifies and further solidifies into a predetermined 3D pattern at room temperature in air. Subsequently, a cellulose hydrogel skeleton was obtained, when the 3D pattern was solvent-exchanged with deionized water. Finally, the mechanical and swelling performance of the cellulose hydrogel scaffold was improved by a cross-linking agent treatment method. With treatment of the 3D printed scaffolds in 0.8 wt% cross-linking agent solution, the obtained cellulose hydrogel could absorb 28 g/g water, and the compression strength was 96 kPa. This work provided an efficient way to prepare natural cellulose hydrogel by 3D printing under room temperature.

“…Most of these were reported to be promising methods but they have certain limitations, which restrict their routine use to some extent. Hence, considering the need for research to develop new alternatives to existing pretreatment methods, nanotechnology could offer promising solutions because it has the potential to change the characteristics of feed materials and biocatalysts used for biofuel production . However, some recent studies have shown that nanotechnology in general and acid‐functionalized magnetic nanoparticles in particular can be used effectively for the pretreatment of some LB .…”

Pretreatment is an inevitable step in the bioethanol / biochemicals production process in which lignocellulosic biomass (LB) is converted to fermentable sugars. It has a large impact on process cost, constituting approximately 40% of total processing cost of bioethanol or biochemical production. Several physical, chemical, physicochemical, and biological pretreatment approaches are available but there are certain limitations to the use of all of these methods on a large scale, which mainly include high processing costs, the generation of toxic inhibitors, and the detoxification of the inhibitors generated. These limitations collectively restrict the use of the existing methods and warrants for the development of a novel, efficient, cost‐effective, and ecofriendly approach for the pretreatment of LB. In this context, nanotechnology‐based pretreatment methods, involving the use of various nanomaterials, have been proposed. The smaller size of nanomaterials makes them more efficient in penetrating the cell walls of LB and hence such nanomaterials can readily interact with the lignocellulosic components at low severity to release carbohydrates to be used for bioethanol and / or biochemical production. This review provides a brief description of various existing pretreatment methods and their advantages and disadvantages. It also presents a critical overview of the application of various nanotechnological methods in the pretreatment of different lignocellulosic substrates. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd

Summary Biofuel is an eco‐friendly alternative source for the depleting fossil fuel resources. The catalytic conversion of biomass into biofuel is an emerging technique in biofuel production. In this study, iron oxide nanoparticles were synthesized from Spinacia oleracea by green synthesis method and subsequently sulfonated to produce active nanocatalyst material. The catalyst obtained has high acid activity and can be readily recovered by an external magnetic field. Corncob waste was crushed to powder form and is subjected to pretreatment by ultrasonication. The compositional analysis was carried out using the Soxhlet extraction method to estimate the cellulose, hemicellulose, and lignin contents. The functional group of biomass and morphology changes were studied by Fourier transform infrared spectroscopy (FT‐IR) and scanning electron microscopy (SEM) analysis. The active nanocatalyst was tested for the hydrolysis of corncob into sugar. The effects of catalyst dosage and temperature on sugar yield were studied. The reducing sugar yield was measured using the dinitrosalicylic acid test. The production of bioethanol from sugar hydrolysate was carried out using a simultaneous saccharification route. A reference sample and the sample with a high yield of reducing sugar were taken into the fermentation process, which was done using Saccharomyces cerevisiae yeast; this yeast was initially cultured in the YPD medium, and the grown yeast was used in the fermentation process for the production of bioethanol, whose yield was confirmed using GC analysis.
