摘要:
为制备生物质废弃物源高性能氮自掺杂活性炭 , 以及阐明活化剂类型对其结构与 CO2 吸附性能的影响规律 , 以太湖蓝藻为前驱体 ,分别采用 NaOH、Na2CO3 和 NaHCO3 活化剂 ,通过热化学活化法制备蓝藻基活性炭材料(X-CAC,X代表活化剂种类 ,CAC表示蓝藻基活性炭);采用电镜、N2/CO2 吸脱附、X射线衍射、Raman光谱、红外光谱和 X射线能谱等方法表征 X-CAC的形貌、孔结构、碳骨架有序性、表面官能团和元素组成等结构;评估X-CAC的 CO2 吸附性能 ,并结合模型拟合探讨 X-CAC的 CO2 吸附行为 。结果表明:3种活化剂均具备良好的成孔能力 ,其中 NaHCO3-CAC具有最高的比表面积、窄微孔数量;X-CAC表面富含含氮和含氧官能团 ,其中 NaHCO3- CAC 的 自掺杂氮含量最高 ,且氮元素主要以吡啶氮形式存在;基于高的窄微孔数量以及高的氮含量 ,NaHCO3-CAC在 0 ℃和 25℃、1 bar条件下对 CO2 的吸附容量可达 4.48 mmol/g和 2.61 mmol/g,高于常见市售活性炭产品 ,且具有优异的选择性、动态 CO2 吸附性能和循环吸附稳定性;X-CAC具有异质吸附表面及强弱 2类吸附位点 ,CO2 在其表面主要以单层和多层混合吸附的复杂方式进行 。该研究可为藻基生物质废弃物的资源化以及藻基活性炭的结构优化和性能提升提供参考。
