Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The electrocatalytic reduction of CO₂ to methanol is explored by the direct comparison of protonated pyridazine and pyridine for their capabilities towards CO₂ reduction. The two materials inherit a significant difference in their pKa values adding valuable information to the ongoing discussion on the nature of CO₂ reduction catalyzed by pyridinium and similar nitrogen containing heteroaromatic systems. Cyclic voltammetry studies as well as bulk controlled‐potential electrolysis experiments were performed combined with product analysis using gas chromatography. Methanol was detected as main CO₂ reduction product in all cases.</p> </abstract>
