High‐Throughput Discovery of Ni(IN)2 for Ethane/Ethylene Separation

Advanced Science, 2021
Although ethylene (C2H4) is one of the most critical chemicals used as a feedstock in artificial plastic chemistry fields, it is challenging to obtain high‐purity C2H4 gas without any trace ethane (C2H6) by the oil cracking process. Adsorptive separation
