A quick guide to the assessment of key electrochemical performance indicators for the oxygen reduction reaction: A comprehensive review

The Effect of Anesthesia Gases on the Oxygen Reduction Reaction

“…The LSV curves are recorded in the 0 to −0.5 V potential range with a potential scan rate of 50 mV/s. The current peak shown in the LSVs, in agreement with the experimental data present in the literature, at about −0.35 V. 2,15,16,17,18 In the case of the solution free of any other gases, a difference is found when comparing the LSV curves recorded with a magnetized electrode (solid line) and the unmagnetized electrode (dashed line). A decrease of about 20% is found in the current at the peak of the LSV when the electrode is not magnetized versus a magnetized one (Table 1).…”

TiO/Ti3O5-Decorated Electrospun Carbon Nanofibers as High-Performance Oxygen Reduction Reaction Electrocatalysts

“…As the global population and energy demand increase, researchers are committed to develop and improve various sustainable energy technologies, such as electrochemical water splitting, − fuel cells, , and metal–air batteries. , The oxygen reduction reaction (ORR) is the key reaction of these green and highly efficient energy conversion technologies that directly transfer chemical energy to electric energy. − However, such reaction is a multistep process with multiple electron transfer, exhibiting very slow reaction kinetics, which severely restrict the performance of related electrochemical devices. − Currently, Pt nanoparticles have been loaded to the surface of the carbon matrix to prepare commercial Pt/C catalysts with excellent ORR activity, which have been widely used in various types of commercialized fuel cells. , Although Pt/C catalysts have unmatched ORR catalytic activity with other related catalysts (especially in acidic medium), it is prone to inactivation during the catalysis process because of various reasons, such as agglomeration, dissolution, and recrystallization of Pt nanoparticles, the corrosion of the carbon matrix, and the poisoning of the catalysts in methanol solution. − Therefore, the development of low-cost non-Pt-based ORR catalysts has important practical significance for improving catalyst stability and promoting the commercial application of related electrochemical devices.…”
