“…[88] Similar observation was reported for the treatment of the pollutants such as NDMA, [70] Ponceau 4R [85] and many others. [70,88] However, at higher Cl À concentrations, lower mineralization rate is always observed due to the formation of larger quantity of recalcitrant organochlorinated byproducts that are highly resistant to the oxidation by electrogenerated BDD( * OH). [85,88,110] It is important to state that a lower Cl À , the organochlorinated byproducts are generated in lower quantity and their influence on the mineralization/organic carbon removal is negligible due to the high oxidation potential of BDD, which can mineralize them to a larger extent.…”

Fast majority of studies on electrooxidation of organic pollutants in Cl À medium have reported a reduction in the mineralization rate/efficiency compared to sulfate or inert media like NaNO 3 or NaClO 4 .…”

“…Based on the existing literature, [87][88][89][90][91] two pathways have been proposed for the formation of RCS from chloride ions during electrooxidation. Diamond electrode is an excellent anode material for conversion of Cl À to RCS during electrolysis of chloride-contain wastewater, especially reversed osmosis concentrate, real textile effluent/washing machine wastewater and others.…”

“…[85,88,[104][105][106][107][108] In most cases, the enhanced degradation was as a result of oxidation of the micropollutants into by-products rather than transformation or polymerization. Indeed, several studies have reported an improvement on the degradation efficiency for different classes of pollutants during electrooxidation with BDD anode in the presence of Cl À ions.…”

Electrooxidation of hazardous organic pollutants contaminating wastewater using thin-film boron-doped diamond (BDD) electrodes is an efficient and well-studied treatment technique. In this review, the three main reactive species, namely: reactive oxygen, chlorine and sulfate species, which can be electrogenerated and then participate in the oxidation processes during electrooxidative wastewater treatment using BDD electrodes, are discussed. The main factors affecting the nature and quantity of the electrogenerated reactive species, specifically the composition of the BDD electrode (doping level and sp 3 /sp 2 ratio) and the operating parameters (working current density and composition of water matrix been electrolyzed) were explained with relative examples. Extensive discussion on mode and reactivity of the three reactive species with organic pollutants during electrooxidation was provided and the future perspectives and direction of research on reactive species generated on BDD electrodes were also discussed.[a] Dr.

Biomass is considered as a promising source to fabricate functional carbon materials for its sustainability, low cost, and high carbon content. Biomass-derived-carbon materials (BCMs) have been a thriving research field. Novel structures, diverse synthesis methods, and versatile applications of BCMs have been reported. However, there has been no recent review of the numerous studies of different aspects of BCMs-related research. Therefore, this paper presents a comprehensive review that summarizes the progress of BCMs related research. Herein, typical types of biomass used to prepare BCMs are introduced. Variable structures of BCMs are summarized as the performance and properties of BCMs are closely related to their structures. Representative synthesis strategies, including both their merits and drawbacks are reviewed comprehensively. Moreover, the influence of synthetic conditions on the structure of as-prepared carbon products is discussed, providing important information for the rational design of the fabrication process of BCMs. Recent progress in versatile applications of BCMs based on their morphologies and physicochemical properties is reported. Finally, the remaining challenges of BCMs, are highlighted. Overall, this review provides a valuable overview of current knowledge and recent progress of BCMs, and it outlines directions for future research development of BCMs.

The oxidation ability of two prominent eco-friendly electrochemical advanced oxidation processes (EAOPs), namely anodic oxidation with H 2 O 2 generation (AO-H 2 O 2 ) and electro-Fenton (EF) for complete abatement of acidic solution of 4-aminophenazone (4-APZ) has been investigated using conductive boron-doped diamond (BDD) and sub-stoichiometric titanium oxide (Ti 4 O 7 ) anodes and carbon-felt cathode. The higher performance of EF compared to AO-H 2 O 2 with either anode was demonstrated. In all trials, 4-APZ was completely destroyed, following pseudo first-order kinetics with the rate constant values increasing with applied current and higher values attained with BDD compared to Ti 4 O 7 anode at similar conditions. The absolute rate constant for the reaction between 4-APZ and hydroxyl radicals was found to be 3.9 � 0.2 × 10 9 L mol À 1 s À 1 . Complete mineralization could be attained with BDD anode, whereas Ti 4 O 7 anode only showed excellent mineralization up to 94 % TOC removal. Therefore, Ti 4 O 7 anode can constitutes a promising anode material thanks to its lower manufacturing cost. Inorganic ions like NO 3 À and HCO 3 À at concentration up to 25 mM has no effect on mineralization efficiency during AO-H 2 O 2 , but the presence of Cl À even at lower concentration of 10 mM significantly reduced the TOC removal efficiency. The toxicity of the solution sharply increased at initial stage of treatment, corresponding to the formation of cyclic by-products but their conversion to carboxylic acids due to longer treatment time involved a sharp toxicity decrease, thus ensuring overall detoxification. * OH)) are generated via water oxidation (Eq. (1)) at the surface of anodes (M). [22][23][24] Besides, when cathodes such carbon felt or gas diffusion cathodes are utilized, weak oxidant H 2 O 2 is generated in large quantities and the process is termed AO-H 2 O 2 .
