α-Al2O3-supported ZIF-8 SURMOF membranes: Diffusion mechanism of ethene/ethane mixtures and gas separation performance

Metal-organic frameworks have been proven to offer the possibility of fabricating highly permeable and selective membranes. ZIF-8 is one of the most studied, attractive, and promising candidates given its known thermal stability and small pores connected by narrow sized windows of around 3.4 Å.
