Abstract
A light-activated hydrogen evolution electrocatalyst is reported. Hydrogen evolves near the thermodynamic potential when aqueous solutions of the iridium chloride complex [Cp*Ir(bpy)(Cl)][Cl] (1, bpy = 2,2′-bipyridine) are illuminated by visible light. In the dark, no electrocatalytic activity is observed. This unique hydrogen evolution mechanism is made possible because a single transition metal complex is the active light absorber and active electrocatalyst. Optimization by tuning the electronic structure of the catalyst and varying reaction conditions resulted in H2 evolution with faster rates, even at milder applied potentials (kobs ∼ 0.1 s–1 at 100 mV electrochemical overpotential).
