Abstract: The performance of a catalyzed H2O2 electrogeneration process using a modified oxygen-fed graphite/PTFE electrode is reported. The organic redox catalyst chosen for incorporation into the graphitic mass was azobenzene. The yield of the hydrogen peroxide is related to the applied potential and to azobenzene concentration. Modification of the gas diffusion electrode with azobenzene improved hydrogen peroxide production, and the overpotential for oxygen reduction was shifted to less negative values compared to the performance of a non-catalyzed electrode, indicating that these modified electrodes have good electro-activity.
