MgZn7O8
MgZn7O8 is a semiconducting spinel oxide catalyst that is theoretically stable enough to be a target for experimental synthesis.
About MgZn7O8
MgZn7O8 is a complex spinel oxide characterized by its semiconducting electronic structure. As a near-hull material, it occupies a favorable energetic position that suggests it is a viable candidate for experimental synthesis and practical integration in catalytic systems.
This compound represents an intriguing intersection of magnesium and zinc chemistry within the spinel framework. Its structural properties make it a subject of interest for researchers seeking to tune catalytic activity through precise elemental substitution and crystalline arrangement.
Key Properties
Cross-validated computational properties for MgZn7O8, aggregated across 3 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.
