Highly efficient visible-light-driven CO₂ reduction to CO using a Ru(<scp>ii</scp>)–Re(<scp>i</scp>) supramolecular photocatalyst in an aqueous solution

Abstract

Even in an aqueous solution, a Ru(<sc>ii</sc>)–Re(<sc>i</sc>) supramolecular photocatalyst worked well for CO₂ reduction. A water-soluble reductant BI(CO₂⁻)H should be useful for evaluation of the real abilities of various photocatalytic systems.
