Fast and selective photoreduction of CO2 to CO Catalyzed by a complex of carbon monoxide dehydrogenase, TiO2, and Ag nanoclusters

Abstract:

Selective, visible-light-driven conversion of CO2 to CO with a turnover frequency of 20 s–1 under visible light irradiation at 25 °C is catalyzed by an aqueous colloidal system comprising a pseudoternary complex formed among carbon monoxide dehydrogenase (CODH), silver nanoclusters stabilized by polymethacrylic acid (AgNCs-PMAA), and TiO2 nanoparticles. The photocatalytic assembly, which is stable over several hours and for at least 250000 turnovers of the enzyme’s active site, was investigat...
