Study of the performance of a cylindrical flow-through electro-Fenton reactor using different arrangements of carbon felt electrodes: effect of key operating parameters

Performance Study of ACET/PTFE Modified Graphite Felt Electrode for Electrocatalytic H2O2 Reaction

“…[9][10][11] And the cathode catalytic materials are usually subjected to hydrothermal activation treatments, 12,13 acid-base treatments, 14,15 and modification treatments such as N, O, F, or metal ion doping, [16][17][18] to modulate the cathode material by increasing its specific surface area, changing its electronic and geometric structure, etc, improved electrocatalytic activity and selectivity for the synthesis of H 2 O 2 . Carbon-based electrodes such as graphite mats, [19][20][21] activated carbon fibers, 22,23 and carbon felts 24,25 have been reported, among which carbon/graphite mats are the most effective in promoting H 2 O 2 production via a two-electron oxygen reduction reaction (2e − -ORR). Hu et al 26 treated rhodamine B solution using the electro-Fenton technique, and the graphite felt cathode treated with H 2 SO 4 was 110.5 mg l −1 .…”
