A pyrene-triazacyclononane anchor affords high operational stability for CO$_2$RR by a CNT-supported histidine-tagged CODH
Résumé
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 6x10$^{6}$ TON when integrated on a gas-diffusion bioelectrode.
