Cesium titanium oxide is primarily utilized in advanced material applications due to its unique optical and electronic properties. It is often employed in the development of photocatalysts, which are critical for environmental remediation processes such as water purification and air cleaning. The compound's ability to absorb light efficiently makes it suitable for use in solar cells, where it enhances energy conversion efficiency. Additionally, cesium titanium oxide is explored in the field of optoelectronics, particularly in the fabrication of light-emitting diodes (LEDs) and sensors, due to its stable and tunable bandgap. Its role in energy storage systems, such as batteries and supercapacitors, is also being investigated for improved performance and durability.
