Polyvinylpyridine polymer show catalytic property to reduce CO2. In electrolyte containing PVP, cyclic voltammetry indicate similar tendency like pyridine molecule catalyst when CO2 gas is purged to electrolyte. PVP coated FTO was used as a cathode for electrochemical cell to reduce CO2 and 360 M of formic acid was produced during the reaction. To reduce CO2 by pyridine groups, multi protons should be supplied to active sites. The Nafion polymer is well known for its water uptake and protons transport properties. Cast Nafion film on the PVP surface enhanced current of CO2 reduction because pyridine groups of PVP is protonated more easily due to the Nafion film. This Nafion/PVP cathode enhanced formic acid production to 660 M at same condition. This polymer composite system provides new insight for CO2 reduction as contrasted with previous researches which used metals as a catalyst for CO2 reduction.
