Large H2 storage capacity of a new polyhedron-based metal–organic framework with high thermal and hygroscopic stability

Abstract

Two metal–organic frameworks (MOFs) based on metal–organic cuboctahedra were prepared using a rigid C₃ 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 ∼4180 m² g⁻¹, high hydrothermal stability, and very promising H₂ sorption properties.
