· NbS

Niobium sulfide (NbS) is a transition metal sulfide compound that combines niobium's refractory properties with sulfide chemistry, creating a material of interest in materials research and specialized industrial applications. This compound is studied primarily for its potential in catalysis (especially hydrodesulfurization and hydrogen evolution reactions), high-temperature applications, and electronic/photonic devices where transition metal chalcogenides offer tunable properties. While not yet a mainstream engineering material like niobium or stainless steel, NbS represents the broader class of layered and non-layered metal sulfides that are gaining traction as alternatives to noble-metal catalysts and in emerging energy conversion technologies.
