Electrocatalytic Properties of Water-Soluble Nickel(II) and Copper(II) Phthalocyaninates in the Oxidation of Hydroxide Ions

The electrochemical and electrocatalytic behavior of gold electrodes modified with tetra-4-sulfophthalocyaninates of nickel(II) (NiPc) and copper(II) (CuPc) is studied in aqueous alkaline solutions using cyclic voltammetry. The electrocatalytic activity of phthalocyaninates of these metals in the ox...

Summary:The electrochemical and electrocatalytic behavior of gold electrodes modified with tetra-4-sulfophthalocyaninates of nickel(II) (NiPc) and copper(II) (CuPc) is studied in aqueous alkaline solutions using cyclic voltammetry. The electrocatalytic activity of phthalocyaninates of these metals in the oxidation of hydroxide ions to form molecular oxygen is assessed and compared with the literature data.
