Carbon dioxide (CO2) is notorious for being a greenhouse gas and is the most important cause of global warming. However, it can be converted into useful products as it is a source of carbon. Reduction of CO2is therefore an attractive research topic for many chemists. Different methods of electrocatalytic reduction of CO2have been reported previously. Since CO2is very stable, the direct electroreduction of CO2into CO requires high potential at −2.2 V versus Ag/AgCl. In this work, CO2reduction was carried out by the photoelectrocatalysis of CO2in the presence of cobalt(III)tetraphenylporphyrin [Co(TPP)Cl] at −1.85 V with a current efficiency of 71%. At illuminated p-type silicon photocathode, the reduction of CO2into CO was performed at a potential of 300 mV which is positive. However, at the same conditions, potential of −1.55 V with a current efficiency ofca65% is required for the carbon electrode.
