Herein, we introduce a new concept of photo-assisted electrochemical CO2 reduction through a translucent thin film electrode. The light-compatible thin film electrode directly exposes Au nanoparticle-loaded Ag nanowires to gaseous CO2, obtaining a CO production rate of 0.7 mmol cm(-2) h(-1) with a photocurrent density of 6.05 mA cm(-2) at -1.1 V-RHE.
