## Abstract A hydrogen peroxide sensing electrode was prepared by incorporating cobalt(II) octaethoxyphthalocyanine [CoPc(OEt)~8~] into a carbon paste (CP) matrix. The CoPc(OEt)~8~โmodified electrode could oxidize hydrogen peroxide at lower potentials than a CP electrode with unsubstituted cobalt p
The interplaying mechanisms involved in the electrocatalytic oxidation of hydrogen peroxide (H202) have been studied using cyclic and differential-pulse voltammetry and X-ray photoelectron spectroscopy (XPS). Cobalt phthalocyanine (CoPC) modified screen-printed carbon electrodes (SPCEs) were used as
