WHAT IS A PHOTOCATALYST?
Photo-Catalysis is defined as “acceleration by the presence of a catalyst”. A catalyst does not change in itself or being consumed in the chemical reaction. This definition includes photosensitization, a process by which a photochemical alteration occurs in one molecular entity as a result of initial absorption of radiation by another molecular entity called the photosensitized. Chlorophyll of plants is a type of photocatalyst called photosynthesis. Photocatalysis is when chlorophyll captures sunlight to turn water and carbon dioxide into oxygen and glucose. Photocatalysis is the creation of a strong oxidation agent to breakdown any organic matter to carbon dioxide and water in the presence of the photocatalyst, light and water.
