The efficient separation of iso-butene, an important raw material in chemical industry, remains challenging due to similar molecular properties of C4 olefins. Here, the authors report a sulfate-pillared adsorbent for the molecular sieving of iso-C4H8 from C4H6 and n-C4H8 with good benchmark uptake ratios and Henry’s selectivities.
