Zn2Ni3O8
Zn2Ni3O8 is a metastable semiconducting oxide compound studied for its potential utility in oxygen-evolution catalytic processes.
About Zn2Ni3O8
Zn2Ni3O8 is a complex ternary oxide categorized within the oxygen-evolution catalyst class. As a semiconducting material, it represents a synthetic challenge due to its position above the thermodynamic hull, suggesting it is a metastable phase that requires specific processing conditions to stabilize. Its structural complexity is highlighted by multiple reported configurations across materials databases. This compound is primarily of interest to researchers investigating novel electrocatalytic surfaces for water splitting. By integrating zinc and nickel into an oxide framework, it serves as a platform for studying how transition metal coordination influences catalytic activity in oxygen-evolving environments.
Key Properties
Cross-validated computational properties for Zn2Ni3O8, aggregated across 3 databases.

How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike the highly stable and widely utilized binary oxide NiO or the layered perovskite-like structures such as LaNiO3 and La2NiO4, Zn2Ni3O8 occupies a more precarious thermodynamic position. While siblings like LiCoO2 and LiMn2O4 are staples in energy storage due to their structural robustness, Zn2Ni3O8 is characterized by its metastable nature, making it a specialized subject for fundamental studies on phase stability rather than a standard commercial catalyst.
