Nano Titanium Oxide: Photocatalytic Properties and Applications
Titanium dioxide (TiO2) is a widely researched photocatalyst due to its unique properties and various applications. Among its many forms, nano titanium oxide has garnered significant attention in recent years. Its photocatalytic properties make it a suitable candidate for environmental remediation, energy production, and various industrial applications.
The photocatalytic process involves the acceleration of a photoreaction in the presence of a catalyst. When exposed to ultraviolet light, TiO2 generates electron-hole pairs, leading to the formation of reactive oxygen species (ROS). These ROS can effectively degrade organic pollutants, making nano titanium oxide an essential material for environmental cleanup.
The synthesis of nano titanium oxide typically involves sol-gel processes, hydrothermal methods, or chemical vapor deposition. The choice of method can significantly influence the properties of the resulting nanoparticles, such as their size, morphology, and surface area. Smaller particles tend to have higher surface areas, enhancing their photocatalytic activity.
