Web4 Jan 2024 · Electrochemical analyses of 1Aq and 2Aq (Pourbaix diagram) suggest the generation of a formal RuV═O species that can potentially promote the oxidation of water. A comparative study of the water oxidation activity catalyzed by 1Aq and 2Aq is reported here to see the effect of a dangling carboxylic group in the catalytic performance. Web21 Oct 2024 · The iron Pourbaix diagram reveals that speciation strongly depends on solution pH [38,39]. At pH values below 9, Fe 2+ is the dominant species, while below pH 4, Fe 3+ dominates. The presence of both Fe species is needed for the cycling of iron in the system, which increases the efficacy of the reaction.
