Here, a transformative platform is reported to derive ultra-thin carbon molecular sieve (CMS) hollow fiber membranes from dual-layer precursor hollow fibers with independently tuned skin layer and substrate properties. These ultra-thin CMS hollow fiber membranes show attractive CO2/CH4 separation factors and excellent CO2 permeances up to similar to 1,400% higher than state-of-the-art asymmetric CMS hollow fiber membranes. They offer a unique combination of permeance and selectivity competitive with zeolite membranes, yet with much higher membrane packing density and potentially much lower costs.
