“…Cellulose, hemicellulose, and lignin are main components of QH. In the IR pattern of QH, the bands and peaks assigned to the groups of these components may be observed [15,16,17,18,19,20]. The bands at 3400 cm −1 and 2900 cm −1 can be assigned to O–H stretching of hydroxyl groups or adsorbed water [15,16].…”

A porous carbon material was prepared from quinoa husk (QH) by carbonization and chemical activation with KOH. A series of experiments, including SEM (Scanning electron microscopy), FT-IR (Fourier transform infrared), XRD (X-ray diffraction), Raman, X-ray photoelectron spectroscopy (XPS), and N2 adsorption/desorption, were carried out on the porous carbon produced from quinoa husk (PC–QH). The results showed that PC–QH was mainly composed of activated carbon and graphite. Moreover, PC–QH exhibited a high level of porosity with a BET (the Brunauer–Emmett–Teller theory) surface area of 1713 m2 g−1. As a representative dye, malachite green (MG) was selected to evaluate the performance of PC–QH to absorb the contaminants in dyeing wastewater. In batch adsorption experiments, PC–QH exhibited a high adsorption rate toward malachite green (MG). An uptake capacity of 599.90 mg g−1 was achieved in the initial 5 min, and the MG adsorption capacity of PC–QH reached 1365.10 mg g−1, which was higher than many other adsorbents. The adsorption data were well fitted with the Freundlich isotherm model and the pseudo-second-order kinetic model. PC–QH also displayed a high absorption rate to rhodamine B (RhB), methyl violet (MV), methylene blue (MB), and methyl orange (MO). The results in this study suggest that PC–QH can be a promising adsorbent for quick treatment of dyeing wastewater.

“…Metal complexation may be another approach for silver deposition that has the advantage of lower silver requirement. In this context, silver loading with high stability and deposition can be achieved by interacting AgNO 3 and KNaC 4 H 4 O 6 ·4H 2 O, whose salt is more environmentally friendly than NaBH 4 at room temperature …”

BACKGROUND Renewable resources have been considered for producing many advanced materials. In this respect, silver‐doped carbon‐based materials with a low loading capacity and high antibacterial activity can also be generated via environmentally friendly routes and from renewable resources. RESULTS Silver‐doped carbon fibers were prepared from wood and cotton fibers via complexation and reduction reactions for depositing silver on the fibers and subsequently via carbonization of the loaded fibers. Silver loading before carbonization enhanced the stability of silver on the carbonized fibers, decreased silver loss (from 30 to 12%) and lowered the silver loading (5.66%) needed to achieve excellent antibacterial activity. However, wood‐based silver‐doped carbon fibers performed better than cotton‐based carbon fibers with respect to loss of antibacterial activity (12% at a silver loading of 5.66% versus 24% at a silver loading of 7.97% in 800 h respectively). These results are attributed to more uniformity in the distribution of silver nanoparticles in the porous structure of wood fibers than in cotton fibers. CONCLUSION The wood‐based carbon fibers exhibited better antibacterial activity and stronger affinity for maintaining silver and lower required silver loadings, and the sequence of silver loading and carbonization was crucial in developing silver‐loaded carbon fibers with good antibacterial performance. © 2019 Society of Chemical Industry

This study describes a green method for preparing all-cellulose nanocomposites through a dissolution and regeneration process. Cotton linter pulp was dissolved in 7 wt % NaOH/12 wt % urea aqueous solution precooled to −12 C. Self-assembly of cellulose molecules into nanostructured cellulose fiber is achieved by using water addition and controlling the temperature to regenerate cellulose. By changing the microenvironment of the cellulose solution, the morphology of the nanostructured cellulose fibers and the mechanical properties of the regenerated cellulose films can be tuned. Then, a series of regenerated cellulose films have been prepared and characterized from various aspects. Compared with other all-cellulose films in the literature, the regenerated all-cellulose nanocomposite films prepared in this work exhibited good optical transparency, thermal stability, and excellent tensile strength (up to 135 MPa) when the regeneration temperature was adjusted to 50 C. This work provided a green and promising approach to prepare high-performance and environmentally friendly all-cellulose nanocomposites.These two authors contributed equally to this work.
