Fotokatalityczn

Fotokatalityczn refers to the phenomenon of photocatalysis, a process that utilizes light to accelerate a chemical reaction. In photocatalysis, a photocatalyst, typically a semiconductor material, absorbs photons from light and becomes excited. This excitation generates electron-hole pairs within the photocatalyst. These charge carriers can then initiate redox reactions on the surface of the catalyst, leading to the degradation of pollutants, water splitting for hydrogen production, or the synthesis of various chemical compounds.

The effectiveness of a photocatalyst depends on several factors, including its band gap energy, surface area, and the presence of co-catalysts. Materials like titanium dioxide (TiO2) are widely studied and used due to their stability, non-toxicity, and strong oxidizing power when illuminated. Other common photocatalysts include zinc oxide (ZnO), cadmium sulfide (CdS), and various composite materials.

Photocatalysis finds applications in environmental remediation, such as air and water purification, where it can break down organic pollutants and kill microorganisms. It is also explored for renewable energy technologies, particularly in the production of hydrogen fuel from water and the conversion of solar energy into chemical energy. Research continues to focus on developing more efficient and cost-effective photocatalytic materials and processes.
