Magnetic Activated Carbon from ZnCl2 and FeCl3 Coactivation of Lotus Seedpod: One-Pot Preparation, Characterization, and Catalytic Activity towards Robust Degradation of Acid Orange 10

Bioinorganic Chemistry and Applications, Год журнала: 2023, Номер 2023, С. 1 - 17

Lotus seedpods (LSPs) are an abundant and underutilized agricultural residue discarded from lotus seed production. In this study, ZnCl2 FeCl3 coactivation of LSP for one-pot preparation magnetic activated carbon (MAC) was explored the first time. X-ray diffraction (XRD) results showed that Fe3O4, Fe0, ZnO crystals were formed in LSP-derived matrix. Notably, transmission electron microscopy (TEM) images shapes these components consisted not only nanoparticles but also nanowires. Fe Zn contents MAC determined by atomic absorption spectroscopy (AAS) 6.89 3.94 wt%, respectively. Moreover, SBET Vtotal prepared with 1080 m2/g 0.51 cm3/g, which much higher than those single activation (274 0.14 cm3/g) or (369 0.21 cm3/g). subsequently applied as oxidation catalyst Fenton-like degradation acid orange 10 (AO10). As a result, 0.20 g/L could partially remove AO10 (100 ppm) adsorption capacity 78.4 mg/g at pH 3.0. When 350 ppm H2O2 further added, decolorized rapidly, nearly complete within 30 min, 66% COD removed 120 min. The potent catalytic performance might come synergistic effect Fe0 Fe3O4 nanocrystals porous support. demonstrated effective stability reusability after five consecutive cycles, when total removal 20 min addition slightly decreased 93.9 ± 0.9% to 86.3 0.8% minimal iron leaching 1.14 1.19 mg/L detected. Interestingly, saturation magnetization 3.6 emu/g easily separated treated mixture next cycle. Overall, findings demonstrate seedpod waste can be low-cost rapid 10.

Advances in the production of fungi-derived lignocellulolytic enzymes using agricultural wastes

Mycology&#58 An International Journal on Fungal Biology, Год журнала: 2023, Номер unknown, С. 1 - 15

Опубликована: Сен. 13, 2023

Lignocellulolytic enzymes play an important role in various industrial applications as well the sustainable valorisation of lignocellulosic materials. Enzyme production using fungi has shown great advantages such high enzyme diversity, efficiency, and availability solid waste raw Agricultural waste, abundant non-food competitive feedstock, can be used to produce fungal lignocellulolytic enzymes. Pretreatment helps break down complex structure material, thereby significantly improving product yield but also requiring more energy consumption. Multiple fermentation technologies, including submerged fermentation, solid-state co-culture, for producing Process optimisation may promote productivity without additional investment. Genetic engineering is useful enhancing meet requirements. This review summarises research progress from agricultural wastes via advanced strategies. It aims provide technical references scale-up
