Webb25 nov. 2024 · To our knowledge, there are no HOR/HER studies on Pt in alkaline conditions using fast mass transport setups, and only RDE data is available. 9,23,24 However, at high pH values the kinetics are at least two orders of magnitude more sluggish (see Fig. 4), and the polarization curves obtained from RDE experiments only overlap the concentration … WebbThe sluggish kinetics of OER limits the overall performance of water electrolysis. Besides, the instability of OER electrocatalysts becomes an even more serious issue under harsh conditions. To describe the performance of electrocatalysts for OER, the overpotential to reach a current density of 10 mA cm −2 (η 10 ) is the most commonly used parameter ( …
