Abstract
A durable molecular photocathode driving CO<sub>2</sub> reduction with over 1200 of turnover number was developed by electropolymerization of Ru(<sc>ii</sc>) complexes. The cell with a suitable photoanode enabled CO<sub>2</sub> reduction with H<sub>2</sub>O oxidation with no bias for 24 h.
