摘　　要：分别采用有序介孔氧化硅SBA-15和NaY分子筛为硬模板合成了系列有序介孔炭OMC和微孔炭CFY.N2静态吸附测试表明,所合成的介孔炭具有丰富的介孔结构和集中的介孔分布.以亚甲基蓝为探针分子,研究其在有序介孔炭OMC和微孔炭CFY上的吸附行为.研究结果表明,有序介孔炭中大于3.5nm的大介孔孔容是决定亚甲基蓝吸附容量和吸附速率的关键因素.吸附动力学理论研究表明,准二级动力学方程可以很好地描述亚甲基蓝分子在介孔炭上吸附动力学行为.Series of ordered mesoporous carbons, OMCs, and mircoporous carbon, CFY, were synthesized using ordered mesoporous silica SBA-15 and NaY zeolite as hard template, respectively. N2 adsorption tests showed that the synthesized mesoporous carbons possess abundant mesopores and centralized mesopore distribution. Methylene blue was used as probe molecule to investigate its adsorption behaviors on OMCs and CFY. Results showed that the mesopores of which the pore size is larger than 3.5 nm is crucial for the adsorption capacity and adsorption velocity of methylene kinetics of methylene blue on mesoporous carbons can model. blue. Theoretical studies showed that the adsorption be well depicted using pseudo-second-order kinetics
