Abstract

Hybrid systems prepared by fixing a Re(I) complex and a dye on three types of TiO₂ nanoparticles in two different ways commonly revealed persistent photocatalysis of the CO₂ reduction to CO with no levelling-off tendency under visible-light irradiation in DMF, giving a turnover number of ≥435.
