Sodium tantalate (NaTaO3) is a perovskite ceramic semiconductor composed of sodium, tantalum, and oxygen. It is primarily investigated in photocatalytic applications, particularly for water splitting and hydrogen generation under UV and visible light irradiation, where its tunable bandgap and crystal structure offer advantages over traditional titania-based photocatalysts. This material remains largely in the research and development phase but shows promise in environmental remediation and renewable energy applications where engineers seek photocatalysts with improved efficiency and stability compared to conventional alternatives.
