Kinetics of Electrocatalytic Oxygen Reduction Reaction over an Activated Glassy Carbon Electrode in an Alkaline Medium

This study focuses on synthesizing hydrogen peroxide using a specially prepared glassy carbon (GC) electrode in a basic solution (0.1 M NaOH). The GC electrode was anodized and tested using several methods like cyclic voltammetry (CV) and rotating disk electrode (RDE) voltammetry. The results showed that oxygen reduction occurred via a two-electron process, producing hydrogen peroxide at a lower potential (−0.35 V vs. Ag/AgCl) than on untreated GC electrodes. The electrode’s catalytic efficiency and properties were also analyzed.
