RuTc
RuTc is a thermodynamically stable metallic alloy of ruthenium and technetium used primarily in catalytic research.
About RuTc
RuTc is a metallic alloy composed of ruthenium and technetium. As a member of the platinum-group alloy catalyst family, it exhibits robust thermodynamic stability, residing directly on the convex hull of its phase space. This stability suggests a well-defined structural integrity that is highly valued in catalytic research. The material is characterized by its metallic nature, lacking a band gap, which facilitates efficient electron transport during chemical reactions. With multiple reported structures across various databases, it represents a significant, data-rich subject for experimental and computational study in the field of advanced materials. Its utility stems from the unique synergy between its constituent transition metals, which are frequently leveraged for their high activity in diverse catalytic processes.
Key Properties
Cross-validated computational properties for RuTc, aggregated across 5 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.
