Large H-2 storage capacity of a new polyhedron-based metal-organic framework with high thermal and hygroscopic stability

Two metal-organic frameworks (MOFs) based on metal-organic cuboctahedra were prepared using a rigid C-3 symmetric ligand, where Zn polyhedron-based MOF (PMOF-2(Zn)) did not show any significant gas sorption behavior, whereas the isostructural Cu polyhedron-based MOF (PMOF-2(Cu)) showed a large surface area of similar to 4180 m(2) g(-1), high hydrothermal stability, and very promising H-2 sorption properties.
