[Figure 3] Schematic diagram illustrating the electrochemical reaction system of H cells using lignin-based carbon catalysts and a comparison of their hydrogen peroxide production rate (IMAGE)
Caption
This figure schematically illustrates the electrochemical reaction in a hydrogen cell under oxygen-saturated conditions using a lignin-based carbon catalyst as the working electrode, showing the process by which hydrogen peroxide is generated through the oxygen reduction reaction. A comparison of the hydrogen peroxide production rate with various reported catalysts confirms that the catalyst developed in this study exhibits high hydrogen peroxide production performance.
