“…During last years, solid catalyst are tested in electro‐Fenton process to extend working pH and reuse possibility. In this context, the use of pyrite seems to be interesting because of self‐setting of solution pH and Fe 2+ concentration ,. This heterogeneous electro‐Fenton process provides almost same treatment efficiency than homogeneous electro‐Fenton with overcoming parts of its drawbacks .…”

Over the past few decades, environmental applications of the boron‐doped diamond (BDD) electrode are reported to be vast and versatile. Applications of BDD electrodes in the field of electrochemical advanced oxidation processes (EAOPs) for the abatement of toxic persistent organic pollutants are significant, owing to the easy and effective way of treatment. This article focuses on highlighting and summarizing the applications of the BDD electrode for the treatment of different synthetic and real wastewaters, such as those involved in pharmaceuticals and personal care products, pesticides/herbicides, dyes, etc. We also review the processes and methodologies involving the synthesis of BDD electrodes and summarize the desirable characteristic features required for the application of EAOPs. Applications of BDD electrodes for the treatment of wastewater through different EAOPs, including anodic oxidation, electro‐Fenton, coupling processes such as electro‐Fenton pyrite, bioelectro‐Fenton, and their recent advancements are also discussed in detail. It envisages the greater potential for complete treatment of different toxic wastewater effluents. This Review shows that the application of BDD electrodes in the field of wastewater treatment is tremendous and proves to be a promising material for future perspectives.

“…In theory, one mole of H2O2 equals to half a mole of oxygen molecules according to the reaction equations [32]. However, in Fenton and Fenton-like reactions, H2O2 could react with hydroxyl radicals, which leads to the low H2O2 utilization efficiency [33]. Therefore, it is significant to study the effect of H2O2 concentration on the degradation efficiency of pollutants.…”

Iron based heterogeneous Fenton catalysts are attracting much attention for its economic and environmental friendly characteristics. In this study, iron oxides loaded carbon cloth (assigned as Fe@CC) was prepared using hydrothermal hydrolysis of Fe(NO 3 ) 3 . The specific surface area of Fe@CC determined by N 2 adsorption-desorption Brunauer-Emmett-Teller method was up to 1325.5 m 2 /g, which increased by 81.8% compared with that of native carbon cloth mainly due to the loading of iron oxide. XPS (X-ray photoelectron spectroscopy) spectra confirmed that the iron oxide on the carbon surface included mainly FeOOH. Its heterogeneous Fenton-like activity was determined using Acid Red G as a model substrate for degradation. Fe@CC maintained high and relatively stable activity during 11 tests, and it showed high COD (Chemical Oxygen Demand) removal efficiency and high apparent H 2 O 2 utilization efficiency. The homogeneous Fenton reaction using the amount of leached Fe(III) suggested that the surficial reaction on Fe@CC was dominant. The stability and the mechanism for gradual decrease of activity during the first 4 tests were also discussed.

“…For EF, it was found that mineralization effectiveness was enhanced by the utilization of pyrite [30][31][32]. Chalcopyrite CuFeS 2 is an antiferromagnetic semiconductor with complex metal oxidation states, including Cu + , Cu 2+ , Fe 2+ , and Fe 3+ , which could contribute to the Fenton process [33].…”
