Efficient H₂O₂ electrogeneration at graphite felt modified via electrode polarity reversal: Utilization for organic pollutants degradation.

ABSTRACT: Electrochemical synthesis of H₂O₂ offers a great potential for water treatment. However, a significant challenge is the development of efficient cathode materials for the process. Herein, we implement a practical electrochemical cathode modification to support efficient H₂O₂ electrogeneration via the reduction of dissolved anodic O₂. Graphite felt (GF) is in situ anodically modified by electrode polarity reversal technique in an acid-free, low-conductivity electrolyte. The modified GF exhibits a significantly higher activity towards O₂ reduction. Up to 183.3% higher H₂O₂ yield is obtained by the anodized GF due to the increased concentrations of oxygen-containing groups and the hydrophilicity of
