Abstract

The CO₂-reduction activity of two Re(I)–NHC complexes is investigated employing a silicon nanowire photoelectrode to drive catalysis. Photovoltages greater than 440 mV are observed along with excellent selectivity towards CO over H₂ formation. The observed selectivity towards CO production correlates with strong adsorption of the catalysts on the photoelectrode surface.
