Electrochemical Reduction of Nitrous Oxide (N₂O) Catalysed by Tetraaminophthalocyanatocobalt(II) Adsorbed on a Graphite Electrode in Aqueous Solution

Abstract

<jats:p> The surface electrochemical response of the Co <jats:sup>II</jats:sup>/ Co <jats:sup>I</jats:sup> redox process of tetraaminophthalocyaninatocobalt(II) ( Co <jats:sup>II</jats:sup> TAPc ) adsorbed on a graphite electrode, was studied in the pH range of 2–13. In aqueous solution, the Co <jats:sup>II</jats:sup> TAPc adsorbed graphite electrode displays very strong electrocatalytic activity toward N <jats:sub>2</jats:sub> O reduction to N <jats:sub>2</jats:sub>, a process which was examined by cyclic and rotating disk electrode voltammetries. The possible application of this Co <jats:sup>II</jats:sup> TAPc modified electrode in N <jats:sub>2</jats:sub> O analysis was explored. </jats:p>
