Ferric iron reduction reaction electro-Fenton with gas diffusion device: A novel strategy for improvement of comprehensive efficiency in electro-Fenton.
TLDR
FRR-EF is proposed, which is operated by applying the optimal potential of ferric iron reduction reaction (FRR) rather than that of 2e-ORR on cathode for EF, thus improving the comprehensive efficiency of EF.About:

Highly efficient dual-cathode Electro-Fenton process without aeration at a wide pH range: Simultaneously enhancing Fe(II) regeneration and mineralization efficiency
TL;DR: In this paper, a dual-cathode electro-Fenton (EF) process using easily available Fe(III) as catalysts for the treatment of organic wastewater at a wide pH range was first proposed, in which natural air diffusion electrode (NADE) was designed as one cathode for H2O2 production without aeration and the modified carbon felt (MCF) was acted as the other cathode mainly for Fe(II) regeneration.
