Selective CO2 adsorption at low pressure with a Zr-based UiO-67 metal–organic framework functionalized with aminosilanes

MOF UiO-67, although without open metal site, was loaded with aminosilanes for selective CO 2 capture. One modified UiO-67 showed a remarkable performance in CO 2 adsorption like huge selectivity of 407 which is 163 times that of pristine UiO-67.
