ELECTROCATALYTIC BEHAVIOR OF TETRASULFONATED METAL PHTHALOCYANINES IN THE REDUCTION OF CARBON DIOXIDE

Abstract
In the electroreduction of carbon dioxide, catalytic activities of the tetrasulfonated metal phthalocyanines(MeTSP) homogeneously dissolved in the Clark–Lubs buffer solutions were investigated by the measurements of current- and capacitance-potential curves. It was found that CoTSP and NiTSP were active but not CuTSP and FeTSP.
