CO₂ reduction with Re(<scp>i</scp>)–NHC compounds: driving selective catalysis with a silicon nanowire photoelectrode

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.
