“…Once again, the significance of the applied current density in the electrooxidation (direct and indirect) process was underlined. Indium doped PbO 2 was used as anode electrode towards the electrocatalytic degradation of aspirin from water bodies by Xia et al [117]. The insertion of indium into the electrocatalytic structure acted beneficially towards the aspirin removal, since the obtained catalytic structure was characterized by a more efficient orientation of the formatted crystallites and smaller size resulting in higher production of ROS and higher oxygen evolution overpotential.…”

Nowadays, the research on the environmental applications of electrochemistry to remove recalcitrant and priority pollutants and, in particular, drugs from the aqueous phase has increased dramatically. This literature review summarizes the applications of electrochemical oxidation in recent years to decompose pharmaceuticals that are often detected in environmental samples such as carbamazapine, sulfamethoxazole, tetracycline, diclofenac, ibuprofen, ceftazidime, ciprofloxacin, etc. Similar to most physicochemical processes, efficiency depends on many operating parameters, while the combination with either biological or other physicochemical methods seems particularly attractive. In addition, various strategies such as using three-dimensional electrodes or the electrosynthesis of hydrogen peroxide have been proposed to overcome the disadvantages of electrochemical oxidation. Finally, some guidelines are proposed for future research into the applications of environmental electrochemistry for the degradation of xenobiotic compounds and micropollutants from environmental matrices. The main goal of the present review paper is to facilitate future researchers to design their experiments concerning the electrochemical oxidation processes for the degradation of micropollutants/emerging contaminants, especially, some specific drugs considering, also, the existing limitations of each process.

“…As a typically representative anode of electro‐catalysis, PbO 2 electrode is recently concentrated more interests and researches on account of its unique properties (Li, Pletcher, & Walsh, 2011; Patel, Bandre, Saraf, & Ruparelia, 2013; Xia et al., 2020). From the perspective of academic investigation, PbO 2 electrode is a considerably excellent target electrode material, which can obtain varying crystal structure, surface morphology, and catalytic oxidation ability with the change of preparation conditions.…”

A novelly modified Ti/PbO 2 electrode was synthesized with Ti 4 O 7 particles through electrochemical deposition method (marked as PbO 2-Ti 4 O 7). The properties of the as-prepared electrodes were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), hydroxyl radical concentration, accelerated life test, etc. Azophloxine was chosen as the model pollutant for electro-catalytic oxidation to evaluate electrochemical activity of the electrode. The experimental results indicated that Ti 4 O 7 modification could prominently improve the properties of the electrodes, especially, improve the surface morphology, enhance the current response, and reduce the impedance. However, the predominant phases of PbO 2 electrodes were unchanged, which were completely pure β-PbO 2. During the electrochemical oxidation process, the PbO 2-Ti 4 O 7 (1.0) electrode showed the best performance on degradation of AR1 (i.e., the highest removal efficiency and the lowest energy consumption), which could be attributed to its high oxygen evolution potential (OEP) and strong capability of HO• generation. Moreover, the accelerated service lifetime of PbO 2-Ti 4 O 7 (1.0) electrode was 175 hr, 1.65 times longer than that of PbO 2 electrode (105.5 hr). © 2020 Water Environment Federation • Practitioner points • PbO 2 /Ti 4 O 7 composite anode was fabricated through electrochemical co-deposition. • Four concentration gradients of Ti 4 O 7 particle were tested. • PbO 2-Ti 4 O 7 (1.0) showed optimal electrocatalytic ability due to its high OEP and HO• productivity.
