FeClO

FeClO is a semiconducting transition metal oxyhalide that functions as a specialized oxide-based oxygen-evolution catalyst. Its position on the thermodynamic convex hull highlights its structural robustness, making it a reliable candidate for electrochemical research where long-term stability is critical. The material is characterized by a well-documented structural profile, supported by multiple entries across major materials databases. Its electronic nature allows for efficient charge transfer, which is essential for facilitating the complex multi-electron processes involved in water splitting and related catalytic reactions. By integrating iron into an oxyhalide framework, this compound offers a unique electronic environment that differs from traditional pure-oxide catalysts.
