Using their new approach, the researchers successfully created 50 cm² graphene membranes—far larger than what was previously feasible—with near-perfect integrity. The membranes demonstrated exceptional CO2 selectivity and high gas permeance, meaning they efficiently let CO2 through while blocking unwanted gases.
Moreover, by optimizing the oxidation process, they were able to increase the density of CO2-selective pores, further enhancing performance. Computational simulations confirmed that improving gas flow across the membrane played a crucial role in achieving these results.
This breakthrough could change the game for carbon capture.
