Biodegradable porous materials based on natural lignocellulosic biomass have multiple advantages of low cost, lightweight, non-toxicity, and the potential in place of non-biodegradable petrochemical products. However, the fabrication process for the porous materials was complicated by the slow and costly prefreeze or supercritical drying methods. Herein, a facile and green/clean strategy was presented to fabricate corncob and willow wood porous materials in ambient conditions. The effect of biomass solution concentration and preparation condition on porous material morphology structure was investigated systematically by scanning electron microscope (SEM). Further, X-ray diffraction (XRD), Fourier transform infrared (FTIR), Brunauer-Emmet-Teller (BET) and thermogravimetric analysis (TGA) were used to estimate the structure and thermostability of the porous materials. Furthermore, the adsorptive properties of the biomass porous materials towards dye methylene blue and oil were evaluated. The biomass porous materials with a fluffy and porous structure were readily obtained via this procedure and showed effective adsorption capacity for dye methylene blue and oil.
基于天然木质纤维素生物质的可生物降解多孔材料具有成本低、重量轻、无毒和潜在可替代不可生物降解的石油化工产品等多种优点。然而，多孔材料的制造工艺复杂，需要缓慢且昂贵的预冷冻或超临界干燥方法。在此，提出了一种在环境条件下制备玉米芯和柳枝多孔材料的简单、绿色/清洁策略。通过扫描电子显微镜（SEM）系统研究了生物质溶液浓度和制备条件对多孔材料形态结构的影响。进一步采用 X 射线衍射（XRD）、傅里叶变换红外（FTIR）、BET 和热重分析（TGA）来评估多孔材料的结构和热稳定性。此外，还评估了生物质多孔材料对染料亚甲基蓝和油的吸附性能。通过该方法可以很容易地得到具有蓬松多孔结构的生物质多孔材料，并且对染料亚甲基蓝和油表现出有效的吸附能力。
