NdMnO3
NdMnO3 is a thermodynamically stable, semiconducting perovskite oxide utilized for its catalytic activity in oxygen-evolution reactions.
About NdMnO3
NdMnO3 is a semiconducting oxide that functions as an effective catalyst for the oxygen-evolution reaction. Its thermodynamic stability on the convex hull makes it a robust candidate for applications requiring long-term material integrity in electrochemical environments.
This compound belongs to the broader family of perovskite-structured oxides, which are highly valued for their tunable electronic properties. By leveraging the interplay between the neodymium and manganese sites, researchers utilize this material to facilitate efficient charge transfer during catalytic processes.
Key Properties
Cross-validated computational properties for NdMnO3, aggregated across 2 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the class of oxygen-evolution catalysts, NdMnO3 serves as a structural analog to LaMnO3, sharing the characteristic perovskite framework that defines many high-performance transition metal oxides. While materials like LiCoO2 and LiMn2O4 are primarily optimized for battery electrode applications, NdMnO3 is specifically distinguished by its stability and catalytic potential in water-splitting architectures compared to simpler binary oxides like NiO.
