While membranes can decarbonize H\n                    <jats:sub>2<\/jats:sub>\n                    \/CO\n                    <jats:sub>2<\/jats:sub>\n                    separation, their moderate H\n                    <jats:sub>2<\/jats:sub>\n                    \/CO\n                    <jats:sub>2<\/jats:sub>\n                    selectivity requires secondary H\n                    <jats:sub>2<\/jats:sub>\n                    purification by pressure swing adsorption. Here, we report hyperselective carbon molecular sieve hollow fiber membranes showing H\n                    <jats:sub>2<\/jats:sub>\n                    \/CO\n                    <jats:sub>2<\/jats:sub>\n                    selectivity exceeding 7000 under mixture permeation at 150\u00b0C, which is almost 30 times higher than the most selective nonmetallic membrane reported in the literature. The membrane is able to maintain an ultrahigh H\n                    <jats:sub>2<\/jats:sub>\n                    \/CO\n                    <jats:sub>2<\/jats:sub>\n                    selectivity over 1400 under mixture permeation at 400\u00b0C. Pore structure characterization suggests that highly refined ultramicropores are responsible for effectively discriminating the closely sized H\n                    <jats:sub>2<\/jats:sub>\n                    and CO\n                    <jats:sub>2<\/jats:sub>\n                    molecules in the hyperselective carbon molecular sieve membrane.
