An increasing demand for sustainable gaseous fuels, such as biomethane and hydrogen, stimulated intensive efforts for developing new technologies and novel materials for gas separation and storage. Herein, a feasible strategy is developed for fabricating metalorganic frameworks (MOFs) nanofiber via combining electrospinning and in-situ growth method for high performance of biogas upgrading and storage. This approach rends the highly porous MOF materials highly distributed on the surface of the PAN nanfiber, which affords the resultant hierarchical porous structures without sacrificing their extraordinary properties such as ultra high surface area, thus contributing to the excellent gas storage capacities. The approach thus providing an promising strategy for structuring MOFs for gas storage applications.
