Abstract

original image

And there was light! Electrochemical studies demonstrated the activation of CO2 by two-electron-reduced ruthenium complex [(bpy)2Ru(Q)]2+ (1). The CO2-reduction cycle was initiated by complex 1 as a photoactive electron mediator. MeOH was afforded with good selectivity from the multicomponent system, which also consisted of cobalt catalyst [Co(NDS)2]2−, a primary alcohol as a co-catalyst, and ascorbic acid in aqueous solution.
