Almost 30 years ago, Lehn et al. (59,60) first reported the photocatalytic reduction of CO2 by a rhenium(I) complex. They found that /ac-Re(bpy)(CO)3Cl (la) could efficiently produce CO from CO2 using TEOA as a sacrificial reductant. The quantum yield ( co) of this reaction was 0.14, and la was the most efficient photocatalyst for CO2 reduction at the time. The other outstanding feature of this photocatalytic reaction is its high-product selectivity. That is, the product produced using la is almost exclusively CO, while most other photocatalytic systems yield H2 and/or formic acid as side products (Table VII). 

CO2 reduction at metallic electrodes is generally poorly selective [151]. Monoelec -tronic reduction of carbon dioxide may occur at a platinum cathode in non-aqueous solvents, but at very negative potentials. Catalytic activation of CO2 has been described (e.g. at a cathode modified by a rhenium complex in a hydroorganic solvent) the observed conversions did correspond to the formation of CO and formic acid. In organic synthesis, CO2 was mainly used as an electrophile (toward electrogenerated anions from jt -acceptors or electrogenerated nucleophiles when adequate transition metals ions were present in situ) for the purpose of carboxylation.
