Electrochemical reduction of CO2 mediated by poly-M-aminophthalocyanines (MÂ =Â Co, Ni, Fe): poly-Co-tetraaminophthalocyanine, a selective catalyst

The electrochemical reduction of CO2 on glassy carbon modified with poly-M-tetrakisaminophthalocyanines (M = Co, Ni, Fe) shows that the cobalt complex is selective giving formic acid as the unique product.
