YFeO2N

YFeO2N is an iron-based oxynitride ceramic compound containing yttrium, representing an emerging class of mixed-anion ceramics that combine oxide and nitride bonding. This material is primarily under investigation in research contexts for energy conversion and catalytic applications, where the dual anion chemistry offers potential advantages in electronic structure and reactivity compared to conventional oxides or nitrides alone. The yttrium-iron oxynitride family is of particular interest for photoelectrochemical devices and heterogeneous catalysis due to the tunable bandgap and enhanced charge transport properties afforded by nitrogen incorporation.
