Abstract

The cooperative effect of pyridine catalysis with photoenhanced electrochemical reduction by CdTe/FTO of CO₂ is explored. The enhancement of overall formic acid production and high faradaic efficiency is due to the increased photocurrent of CdTe/FTO upon irradiation and the decrease in activation barrier due to the formation of a pyridine–CO₂ intermediate.
