摘    要:提出采用黄孢原毛平革菌对生物质前体物进行预处理的制备策略,从而研发孔结构可调的多级孔炭材料模板.选用荷叶作为生物质原材料,探讨菌种投加量、培养时间对多级孔炭材料前驱体的影响,并采用水蒸气物理活化法,分析活化温度和活化时间对炭材料比表面积、孔径分布和表面官能团的综合作用.最后,通过Raman、XRD、BET、FTIR、TGA、SEM、EA等手段表征其物理化学性质,并考察真菌预处理对炭材料的甲苯吸附性能的影响.结果表明,在生物质荷叶质量30 g、菌种投加量4 mL、培养时间7 d、活化温度800℃、活化时间90 min条件下制备的微介多级孔炭材料,在含有较多介孔的前提下比表面积可达937 m~2·g~(-1),总孔容为0.68 cm~3·g~(-1).动态模拟吸附实验发现,经预处理的炭材料在甲苯浓度905 mg·m~(-3)下对其饱和吸附容量为304 mg·g~(-1),是未经真菌调控荷叶吸附容量的1.83倍,吸附性能的提升主要归因于比表面积、孔容及表面酸性基团增大的作用.经真菌预处理调控的炭材料对甲苯的吸附符合Langmuir吸附等温线,属于单分子层吸附.

关 键 词:微介多级孔炭材料  黄孢原毛平革菌  调控  木质素  甲苯
