Structural-failure resistance of metal-organic frameworks toward multiple-cycle CO2 sorption.

Published in: Chemical communications (Cambridge, England) (2017)

We present the first study on the structural-failure of MOFs induced by multiple-cycle CO2 adsorption and desorption, wherein UiO-66(Zr) demonstrates a much better resistance than HKUST-1 in 500-cycle CO2 adsorption-desorption tests. This conclusion is supported by the higher elastic modulus of UiO-66(Zr) (ca. 28 GPa) and retention of elastic modulus (100%) than HKUST-1 (ca. 19 GPa, 64%) measured via multifrequency atomic force microscopy (MAFM).
