Key Points

The study aims to understand how Co can prevent the over-oxidation of RuO2 during acidic water electrooxidation.
Pt was impregnated into the RuO2 phase with oxophilic Co to assess its effect on oxidation.
The assessment was conducted under acidic conditions to simulate water electrooxidation.
The addition of Co significantly suppressed Ru over-oxidation during electrooxidation activities.
Enhanced stability of the RuO2 phase was observed in the presence of Co, indicating its role in protecting against oxidation.

Implication

Investigates over-oxidation of Ru in acidic water electrooxidation, suggesting Co may enhance stability.

Abstract

Pt impregnated into the RuO 2 phase assisted by oxophilic Co suppresses the over-oxidation of Ru during water electrooxidation under acidic conditions.
