Abstract

The structure transition of flexible MOF (MIL-53) can be adjusted by confinement of BNH_x into MIL-53 channels. Hydrogen and carbon dioxide adsorption properties are also improved by incorporating BNH_x. At 77 K and 1 atm pressure hydrogen storage capacity can reach 2.0 wt% and CO₂ adsorption capacity is 4.5 mmol g⁻¹ at 273 K 1 atm.
