以四水合硝酸铟为金属盐、1,3,5-三(4-羧基苯基)苯(BTB)为配体、冰醋酸为模板剂,利用金属离子(In3+)与BTB的配位自组装特性,采用溶剂热法制备了非穿插型金属有机骨架材料(MOF)(In-BTB).通过XRD、TG、N2吸附-脱附等温线对其进行了表征,探究了 In-BTB对甲烷的吸附量和工作能力.结果表明,In-BTB具有较高的比表面积(2487 m2/g)和永久孔隙结构,孔体积为1.07cm3/g.在273 K、8 MPa条件下,In-BTB对甲烷的质量工作能力为397 cm3/g(0.29 g/g).该材料还表现出良好的可重复性,在273 K、8 MPa条件下原位测试3次后,甲烷工作能力仍能保持在380 cm3/g以上.
Synthesis,structure,and methane storage capacity of an indium-based organic framework
Non-interpenetrating metal-organic framework(MOF)(In-BTB)were prepared by solvothermal method using indium nitrate tetrahydrate as metal salt,1,3,5-tri(4-carboxyphenyl)benzene(BTB)as ligand and acetic acid as template,taking advantage of the self-assembly properties of metal ion(In3+)and BTB.The MOF In-BTB was characterized by XRD,TG and N2 adsorption-desorption isotherm,and evaluated for its adsorption and storage capacity for methane.The result showed that In-BTB exhibited a high specific surface area of 2487 m2/g and a permanent porous structure with a pore volume of 1.07 cm3/g.The mass working capacity of In-BTB for methane was 397 cm3/g(0.29 g/g)at 273 K and 8 MPa.The In-BTB also showed good repeatability,with the methane working capacity remaining above 380 cm3/g after three in-situ tests at 273 K and 8 MPa.
