摘　　要：采用二甲氧基甲烷对四苯基硼酸钠进行Friedel-Craft烷基化,得到了一种具有阴离子骨架的介孔材料MPTB-1。借助气体吸附仪和紫外分光光度计对该材料氢气存储性能和常见有机染料分子的吸附性能进行研究。结果表明,材料孔径分布在5.3 nm附近,属于介孔材料;在分压0.1 MPa时可以吸附1.19%(质量分数)的氢气;该材料对阳离子染料罗丹明B具有较高的吸附效率,对水中染料去除率30 min可达99%以上;MPTB-1对罗丹明B的吸附等温线符合Langmuir模型,吸附动力学符合准二级动力学模型。表明材料对罗丹明B的吸附为均匀的单分子层吸附,而且两者之间存在化学吸附作用。The sodium tetraphenylborate was subjected to Friedel-Craft alkylation using dimethoxymethane to obtain mesoporous polytetraphenylborate-1(MPTB-1)with anionic skeleton.The hydrogen storage properties and adsorption properties of common organic dye molecules were studied with the aid of by gas adsorption instrument and UV spectrophotometer.The results showed that the pore size distribution of the material is around 5.3 nm,which indicated MPTB-1 belongs to mesoporous material.Besides,1.19%hydrogen can be adsorbed at a partial pressure of 0.1 MPa;the material exhibited remarkable adsorption rate for the cationic dye rhodamine B:the removal rate can up to 99%within 30 min.Furthermore,the adsorption isotherm and the adsorption kinetics consisted with the Langmuir model and the quasi-secondary kinetic model,respectively.It is indicated that the adsorption of Rhodamine B on the material is uniform monolayer adsorption,and the adsorption process tends to be chemical adsorption.
