A Pyrene‐Triazacyclononane Anchor Affords High Operational Stability for CO(2)RR by a CNT‐Supported Histidine‐Tagged CODH

An original 1‐acetato‐4‐(1‐pyrenyl)‐1,4,7‐triazacyclononane (AcPyTACN) was synthesized for the immobilization of a His‐tagged recombinant CODH from Rhodospirillum rubrum (RrCODH) on carbon‐nanotube electrodes. The strong binding of the enzyme at the Ni‐AcPyTACN complex affords a high current density...

description An original 1‐acetato‐4‐(1‐pyrenyl)‐1,4,7‐triazacyclononane (AcPyTACN) was synthesized for the immobilization of a His‐tagged recombinant CODH from Rhodospirillum rubrum (RrCODH) on carbon‐nanotube electrodes. The strong binding of the enzyme at the Ni‐AcPyTACN complex affords a high current density of 4.9 mA cm(−2) towards electroenzymatic CO(2) reduction and a high stability of more than 6×10(6) TON when integrated on a gas‐diffusion bioelectrode.
