Herein we present the synthesis of continuous and reproducible Bio-MOF-1 membranes. These membranes displayed high CO2 permeances for equimolar mixtures of CO2 and CH4. The observed CO2/CH4 selectivities above the Knudsen selectivity suggest that the separation is promoted by preferential CO2 adsorption over CH4. This preferential CO2 adsorption was attributed to the presence of adeninate amino basic sites present in the Bio-MOF-1 structure. Our work demonstrates the feasibility of the development of a novel family of membranes that could be promising for diverse molecular gas separations. To our best knowledge, we demonstrate for the first time: a) the synthesis of any continuous Bio-metal organic framework membrane and b) the ability of these membranes to separate CO2/CH4 gas mixtures.
