AI Technical Summary
The small gas-liquid-solid three-phase reaction interface of traditional gas diffusion electrodes results in low oxygen utilization and low efficiency of hydrogen peroxide production, making it difficult to rapidly produce large quantities of hydrogen peroxide.
Design an inverted U-shaped electrochemical reactor comprising a cathode and an anode reaction chamber. Use particle electrodes to fill the particle electrodes. The reactor is a three-phase reactor provided by a particle electrode bed. The particle electrodes are spherical or irregular in shape and have an appropriate filling height. Combined with an ion exchange membrane and a highly conductive electrode rod, a highly efficient gas-liquid-solid three-phase contact point is formed.
It improves oxygen utilization and hydrogen peroxide production efficiency, enabling efficient distributed hydrogen peroxide production, and is suitable for the energy and environmental sectors.
