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.
