Sulfate-Pillared Adsorbent for Efficient Acetylene Separation from Carbon Dioxide and Ethylene.

ABSTRACT: The effective separation of acetylene (C₂H₂) from carbon dioxide (CO₂) and ethylene (C₂H₄) presents considerable challenges in the petrochemical industry. In this work, we report a novel sulfate-pillared (SO₄ ^2-) ultra-microporous material, denoted as SOFOUR-DPDS-Ni (SOFOUR = SO₄ ^2-, 4-DPDS = 4,4'-dipyridyldisulfide), for efficient C₂H₂ capture from both CO₂ and C₂H₄. The sulfate pillars play a crucial role in inducing robust negative electrostatic potentials within the intralayer cavities and interlayer channels, thereby facilitating the selective recognition of C₂H₂. As a result, SOFOUR-DPDS-Ni demonstrates a remar
