Efficient Photocatalysts for CO2 Reduction

Inorganic Chemistry, 2015
Abstract Three types of photocatalytic systems for CO2 reduction, which were recently developed in our group, are reviewed. First, two-component systems containing different rhenium(I) complexes having different roles; i.e., redox photosensitizer and catalyst in the reaction solution are described.
