What is Photocatalyst

Photocatalysis

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. Photocatalysis compared to photosynthesis, in which chlorophyll captures sunlight to turn water and carbon dioxide into oxygen and glucose, photocatalysis creates strong oxidation agent to breakdown any organic matter to carbon dioxide and water in the presence of photocatalyst, light and water.

  1. Anti-Bacterial Effect
    • Photocatalyst does not only kill bacteria cells, but also decompose the cell itself. The titanium dioxide photocatalyst has been found to be more effective than any other antibacterial agent, beacause thw photocatalytic reaction works even when there are cells covering the surface and while the bacteria are actively propagating. The end toxin produced at the death of cell is also expected to be decomposed by photocatalytic reaction. Titanium dioxide does not deteriorate and it shows as long-term anti-bacterial effect. Generally speaking, disinfections by titanium oxide is three times stronger than chlorine, and 1.5 times stronger than ozone.
  2. Deodorizing Effect
    • In deodorization applications, hydroxyl radicals accelerate the breakdown of any organic compound (VOC) by destroying the molecular bonds. Some examples of odor molecules include: Smoke odor, formaldehyde, nitrogen dioxide, urine and fecal odor, gasoline, and many other hydrocarbon molecules in the atmosphere. Air disinfection through photocatalysis decomposes smoke, pollen, bacteria, viruses, and free bacteria in the air with a filtration rate of 99.9% with the help of the high oxidative effect of the photocatalyst derivatives.
  3. Air Purification Effect
    • Photocatalysis can be applied to reduce up to 99.9% of air pollutants such as Nox, cigarette smoke, as well as volatile compounds resulting from various building materials. Additionally, photocatalytic protection can be applied to light covers and tunnel walls to prevent soot deposition. Suspended compounds such as chlorofluorocarbons (CFCs) and CFC substitutes, some greenhouse gases, and nitrogen and sulfur compounds undergo photochemical reactions either directly or indirectly in the presence of light until their final decomposition.
  4. Anti-Fog Effect and Self-Cleaning
    • Most of the exterior walls of buildings are soiled by soot. When building materials are coated with a photocatalyst, the surfaces of the building become self-cleaning, antistatic, oxidative, and hydrophilic. Hydrocarbons are oxidized and pollutants are removed through gravity and rain.
  5. Water Purification
    • Photocatalyst coupled with UV lights can oxidize organic pollutants into nontoxic materials, such as CO2 and water and can disinfect certain bacteria. This technology is very effective at removing further hazardous organic compounds (TOCs) and at killing a variety of bacteria and some viruses in the secondary wastewater theatment. Pilot projects demonstrated that photocatalytic detoxification systems could effectively kill fecal coli form bacteria in secondary wastewater treatment.
