About Cd1Rh2Ti1
Cd1Rh2Ti1 belongs to the class of platinum-group alloy catalysts, characterized by its semiconducting electronic nature. As a complex ternary intermetallic, it represents a unique combination of cadmium, rhodium, and titanium within the broader landscape of transition metal alloys.
While this compound is currently identified as being above the thermodynamic hull, it remains a subject of interest for researchers mapping the structural diversity of platinum-group alloys. Its existence across multiple reported structures highlights the ongoing effort to synthesize and characterize complex metallic phases for potential catalytic utility.
Key Properties
Cross-validated computational properties for Cd1Rh2Ti1, 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.
