Abstract

A highly negative overpotential is required to electrochemically reduce CO2 owing to its chemical inertness. A key to solve this problem is how to activate CO2 at electrode, and the development of electrocatalytic process with an electrode mediator is very important. We have proposed a catalytic process of CO2 reduction at the modified electrode having two laminated films consisting of an inorganic conductor and a conducting polymer. As the inorganic conductor and the conducting polymer, Prussian blue (PB) and polyaniline (PAn) were used, respectively. In the present study, various metal complexes were fixed onto the conducting polymer, and the activation process of CO2 reduction was monitored with in situ Fourier transform infrared spectroscopic (FTIR) method.1,2)
