Adjustable structure transition and improved gases (H-2, CO2) adsorption property of metal-organic framework MIL-53 by encapsulation of BNHx

摘要

The structure transition of flexible MOF (MIL-53) can be adjusted by confinement of BNHx into MIL-53 channels. Hydrogen and carbon dioxide adsorption properties are also improved by incorporating BNHx. 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.
