BiFeON2

BiFeON2 is an experimental oxynitride ceramic compound combining bismuth, iron, and nitrogen — a material class that bridges traditional oxides and nitrides to achieve novel electronic and catalytic properties. This research-phase compound is primarily investigated for photocatalytic applications under visible light, leveraging the bandgap narrowing that oxynitride structures provide compared to pure oxides. Its potential extends to environmental remediation and sustainable energy applications, though it remains largely a laboratory material rather than a commercialized engineering material.
