A novel core-shell Fe@Co nanoparticles uniformly modified graphite felt cathode (Fe@Co/GF) for efficient bio-electro-Fenton degradation of phenolic compounds

Self-Growing MZIF8/GDE Bonding by N–Zn–O Boosts Electrochemical Oxygen Reduction to H2O2

“…Self-growing gas diffusion electrodes have attracted attention because of the low resistance to electron transfer versus substance transfer. The reduction of the electronic mass transfer resistance is owing to the elimination of the use of binders. , For example, self-growing PtCu nanowire arrays on carbon paper prepared without binders by Li et al significantly reduced the electronic mass transfer resistance in formic acid fuel cells, and Zhang et al used the integrated features between catalyst and support to enable extremely efficient charge transfer, resulting in unprecedented water oxidation activity and exhibiting excellent system stability. In the electrocatalytic oxygen reduction process to produce H 2 O 2 , the diffusion of oxygen and products is also important.…”

Efficient Chloroquine Removal by Electro-Fenton with FeS2-Modified Cathode: Performance, Influencing Factors, Pathway Contributions, and Degradation Mechanisms

“…To this end, various materials such as nitric acid, reduced graphene oxide, and zeolitic imidazolate framework-8 have been applied to modify the CF or graphite felt (GF) cathode electrode. The second is to add iron-based chemical catalysts to electrolytes or directly modify the cathode with iron-based compounds. − Layered double hydroxides, zero-valent iron, MIL-101(Fe), Mn/Fe@porous carbon, and minerals-like pyrite (FeS 2 ) have been proved to be outstanding catalysts to improve the performance of the EF process . In particular, FeS 2 , one of the most abundant natural iron minerals on earth, can be a potential candidate to provide an acidic environment required for the EF process and self-regulate Fe 2+ in the aqueous solution via eqs –. , 2 FeS 2 + 7 normalO 2 + 2 normalH 2 normalO → 2 Fe 2 + + 4 SO 4 2 − + 4 normalH + 2 FeS 2 + 15 normalH 2 normalO 2 → 2 Fe 3 + + 14 normalH 2 normalO + 4 SO 4 2 − + 2 normalH + 2 FeS 2 <...…”

A review on bio-electro-Fenton systems as environmentally friendly methods for degradation of environmental organic pollutants in wastewater

“…3). 53 In recent years, the feasibility of the BEF system to treat of a wide range of synthetic wastewaters, which contains a variety of environmental organic compounds, such as dyes, 63–67 industrial pollutants, 68–70 and pharmaceutical compounds 71–73 has been demonstrated. In this review, the mechanisms and configuration of the BEF systems are described.…”
