Niobium nitride is a compound of niobium and nitrogen (nitride) with the chemical formula NbN. At low temperatures (about 16 K) NbN, niobium nitride becomes a superconductor, and is used in detectors for infrared light.
- Niobium nitride's main use is as a superconductor. Detectors based on it can detect a single photon in the 1-10 micrometer section of the infrared spectrum, which is important for astronomy and telecommunications. It can detect changes up to 25 gigahertz.
- Niobium nitride is also used in absorbing anti-reflective coatings.
- In 2015, it was reported that Panasonic Corp. has developed a photocatalyst based on niobium nitride that can absorb 57% of sunlight to support the decomposition of water to produce hydrogen gas as fuel for electrochemical fuel cells.
