Adjustable structure transition and improved gases (H _2, CO _2) adsorption property of metal-organic framework MIL-53 by encapsulation of BNH _x

摘要

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 CO _2 adsorption capacity is 4.5 mmol g ~(-1) at 273 K 1 atm.
