High methane storage and working capacities in a NbO-type metal–organic framework

Abstract

To improve methane adsorption by pore structure optimization, we developed a new organic linker and used it to construct a NbO-type metal–organic framework ZJNU-53 that, after activation, exhibits exceptionally high methane storage and working capacities of 241 and 190 cm³ (STP) cm⁻³ at 298 K and 65 bar, respectively, if the packing loss is not considered, which are among the highest reported for MOF materials.
