Fotokatalyyttisiin

Fotokatalyyttisiin refers to processes driven by photocatalysis. Photocatalysis is a chemical reaction that is caused by light. In this process, a substance called a photocatalyst absorbs light energy and uses it to accelerate a chemical reaction. The photocatalyst itself is not consumed in the reaction. A common example is titanium dioxide (TiO2), which is used in applications like self-cleaning surfaces and air purification. When exposed to ultraviolet (UV) light, TiO2 can break down organic pollutants and kill bacteria. The effectiveness of photocatalysis depends on several factors, including the type of photocatalyst, the wavelength and intensity of the light source, and the nature of the substance being reacted. This technology has potential applications in environmental remediation, energy production, and medicine. For instance, photocatalytic water splitting can produce hydrogen fuel, and photocatalytic degradation can remove harmful chemicals from water and air. Research continues to explore new photocatalysts and optimize existing ones for a wider range of applications.
