semiconductor· TaON
Tantalum oxynitride (TaON) is a ternary ceramic semiconductor compound combining tantalum oxide and nitride phases, belonging to the class of transition metal oxynitrides. It is primarily investigated in photocatalysis and photoelectrochemical applications, particularly for solar water splitting and environmental remediation, where its tunable bandgap and nitrogen doping provide advantages over pure tantalum pentoxide in visible-light absorption. The material remains largely in research and development stages but shows promise as an alternative to more established photocatalysts like TiO₂ due to its enhanced light-harvesting capability and potential for scalable synthesis.
