Synergism between CdTe semiconductor and pyridine – photoenhanced electrocatalysis for CO2 reduction to formic acid†
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.
