Abstract:

The electrochemical behaviour of Cu2O in various solvent systems was investigated using chronoamperometry (CA) technique. In water, the chronoamperometry plot revealed a transition from dominant charging current to Faradic current at higher potentials, with irregular behaviour observed above 1.0 V. Diffusion coefficients decreased with increasing potential and time period, exhibiting a linear relationship. In the water-sulphite system, an increase in area of the curve was observed with increasing potential, with the peak current decreasing over time. Diffusion coefficients varied with potential and pH, with lower values observed at pH 1.8 and 2.0. In DMSO, chronoamperometry plots showed a linear relationship between charging and Faradic current, with diffusion coefficients increasing with potential and time period. In DMSO + SO2, increasing potentials led to higher slope values, indicating a rise in diffusion coefficients. Overall, the study elucidates the electrochemical properties of Cu2O in different solvent systems, providing insights into its behaviour under varying conditions.
