The simultaneous electrocatalytic reduction of carbon dioxide and dinitrogen was investigated at 60 bar (30 bar N-2+30 bar CO2) in this study. The electrochemical reduction was achieved on polyaniline (PAni) and polypyrrole (PPy) coated platinum electrodes at -0.165V, the lowest possible overpotentials, known in the literature. The main products from the CO2 and N-2 reduction were ammonia, urea and formic acid. The electrochemical reduction performed in an aqueous 0.1 M Li2SO4/0.03 MH+ solution was characterized by using cyclic voltammetry, potentiostatic electrolysis and Tafel diagrams in order to analyze the polymer selectivity as well as its reactivity as a function of the applied potential. Hence, CO2 and N-2 were converted into value added chemicals, which included urea; an important raw material for the chemical industry with high nitrogen content.eninfo:eu-repo/semantics/embargoedAccessN-2-ReductionCO2-ReductionConducting PolymerUrea FormationArticle181889310.1016/j.apcatb.2015.07.045WOS:000364256000010N/A
