Accelerating effect of a proton on the reduction of CO2 dissolved in water under acidic conditions. Isolation, crystal structure, and reducing ability of a water-soluble ruthenium hydride complex.
A water-soluble hydride complex [(eta6-C6Me6)RuII(bpy)H]+ {1, bpy = 2,2'-bipyridine} serves as a robust reducing agent for the reduction of CO2 in water in a pH range of about 3-5 at ambient temperature under stoichiometric conditions. The structure of 1 was unequivocally determined by X-ray analysis. The mechanism of acid-catalyzed reduction of CO2 promoted by 1 in water under acidic conditions is disclosed.
