Abstract

An overall PEC CO₂ conversion was firstly reported by integrating both the newly designed metal cathode and the n-type photoanode with functional nanostructures. The maximum Faradaic efficiency (FE) for CO is ca. 75% at −1.2 V with incident photon-to-current conversion efficiency (IPCE) value of 16% at 340 nm.
