Abstract
Detailed neutron powder diffraction (NPD) experiments were carried out on the bare and CO2 adsorbed Mg-MOF 74. While low-temperature data revealed two CO2 adsorption sites and multiple changes in the framework as a function of CO2 loading, room temperature data revealed minimal changes in unit cell volumes with adsorption up to 1.0 CO2/Mg (≅ 27 mass fraction, wt %). Further, temperature dependent data collected on the bare framework reveals zero thermal expansion over a wide range of temperatures, 10 K to 475 K.Citation
