Implication

Experimental study demonstrates reversible, poison-tolerant olefin binding using nickel dithiolene complexes, suggesting an electrochemical route for industrial olefin purification.

Key Points

To evaluate the feasibility and electrochemical control of nickel dithiolene complexes for the selective, reversible separation of olefins from complex gas mixtures containing common impurities.
Tested selective and reversible binding of light olefins (ethylene and propylene) using the metal complex Ni[S2C2(CF3)2]2.
Exposed the complex to common gas-stream poisons, including hydrogen gas, carbon monoxide, acetylene, and hydrogen sulfide, to assess ligand-centered binding tolerance.
Investigated electrochemical control over olefin binding and release kinetics across different oxidation states of Ni[S2C2(CN)2]2^n (n = 0, -1, -2).
The Ni[S2C2(CF3)2]2 complex bound light olefins selectively and reversibly via sulfur ligands without being deactivated by hydrogen gas, carbon monoxide, acetylene, or hydrogen sulfide.
Reversible olefin binding and release occurred rapidly on the electrochemical time scale via modulation of the oxidation state in Ni[S2C2(CN)2]2^n.
