Abstract Carbon capture and utilization (CCU) is one of the critical environmental and energy issue due to the greenhouse gas effect. Notably, the (photo)electrochemical reaction of CO2 reduction in an aqueous electrolyte has got great attention as an alternative approach for the effective CCU. In photoelectrochemical or electrochemical reactions there are several advantages, 1) the selectivity of products can be adjusted by applied potential and 2) the driving force for CO2 reduction can be obtained from a renewable energy source like solar light. However, in an aqueous electrolyte condition, hydrogen evolution reactions can compete with CO2 reduction. Therefore, developing the selective catalysts is a key factor for efficient CO2 reduction reactions. The rhenium based organometallics has been utilized for CO production from the CO2 reduction, but most of the cases were carried out in organic solvent conditions. In this study, we have investigated the activity of Re-based complexes for CO2 reduction in an aqueous electrolyte, with a carbon electrode and a semiconductor photocathode as an electron source.
