“…Besides the controlled chemical deposition method, the bimetallic Ti/Pt with one‐sided or double‐sided Pt coating of 3–10 μm on Ti foil could also be manufactured by metallurgical method, contacting explosion welding with further rolling. Assembled into a treatment unit with a capacity of 500 mL/min, main performance characteristics of the electrolyzers including required current load, working surface of electrode, mass transport factors, effect of gas filling on the dynamics of electrolysis and heat balance were detailly investigated [47] . Plate electrodes containing Pt group metal including Ti/Pt, Ti/(Pt−Ir) 70:30 , Ti/RuO 2 , Ti/(RuO 2 ‐TiO 2 ) 40:60 , Ti/(RuO 2 ‐TiO 2 ‐IrO 2 ) 20:60:20 , and Ti/(Ta 2 O 5 ‐IrO 2 ) 70:30 were evaluated on the aspects of decomposition rate, current efficiency and the stability by Simka et al [48] .…”

Urea has been regarded as an important chemical compound in the food‐water‐energy nexus. However, the emission of urea from human activity, industrial manufacture, and agricultural fertilization into the environment has caused an ecological nitrogen imbalance. Besides addressing the environmental pollution, the applications of clean energy conversion from urea‐rich wastewater has strong potential for resource and energy recovery. Herein, we conducted a comprehensive overview of electrochemical urea oxidation reaction (UOR) for pollution control and energy harvesting. The present mechanisms and behaviors of UOR under different water matrices have been characterized and compared in detail. Additionally, the latest development of electrochemical UOR integrated into electrolyzers and fuel cells are presented. Finally, we discuss the prospects and challenges of UOR technologies, suggesting several directions for the electrochemical conversion of urea‐abundant wastewater in the near future.

Investigations on the anodic decomposition of urea using Ti/Pt and Ti/(RuO 2 -TiO 2 ) 40:60 electrodes were carried out. The kinetics of the process were examined in a periodic electrolyser. The effect of anodic current density, initial urea concentration, and sodium chloride concentration on the effectiveness of the basic process (average rate of urea decomposition, current efficiency, and unit power consumption) is discussed. When a Ti/Pt electrode is applied for urea removal from aqueous solution urea is not decomposed directly at the surface of the electrode, but rather in the bulk of the solution by hypochlorite formed during the process. When the Ti/(RuO 2 -TiO 2 ) 40:60 electrode is used for the removal of urea from aqueous solutions, the reaction of urea with chlorine adsorbed at the electrode predominates. In both cases non-toxic products of urea decomposition (N 2 , CO 2 ,) are formed. Comparison of the effectiveness of anodic decomposition of urea for the Ti/Pt and Ti/(RuO 2 -TiO 2 ) 40:60 electrodes in the periodic electrolyser at optimum process parameters has revealed that the former electrode is more favorable.

“…A voltage of 3.5 V was applied across each EO unit. Every 30 min, the electrode polarity was inversed to eliminate deposits (e.g., Mg salts) that may form on the electrodes (11 [albumin] appeared to be below detection limit and were therefore only measured in plasma in the remaining experiments ([Fe 2ϩ ] at the start and end of the experiment and [albumin] hourly). Hemoglobin was monitored hourly and leukocytes and thrombocytes at the start and end of the experiment (note that leukocyte and thrombocyte counts at the start and end were lacking in 2 and 4 experiments, respectively).…”
