How Does Photocatalysis Work?
Photocatalysis is a well-known physical principle that provides powerful and everlasting disinfection. The titanium dioxide, (the catalyst) is not consumed in the reaction. The visible and ultraviolet energy spectrum of normal daylight activates the titanium dioxide nanocrystals (TiO2) on the surface producing a photocatalytic effect. The surface of our product is activated by light with a wavelength under 420 nm (Visible and UV), the minimal amount required for safe, effective activation is 0.2W/m2.
The product firmly adheres to the surface with 3-5 MPa. No pollutants or any particles are released into the environment.
This means that the titanium dioxide nanocrystals absorb the UV light energy, producing free electrons and electron holes. The direct interaction of electrons and electron holes with molecules from the surrounding environment effectively oxidize, and thus decompose, a wide range of harmful organic molecules, including bacteria, viruses, and volatile-organic-compounds (VOCs). Additionally, light and TiO2 nanocrystals prevent the establishment and growth of microorganisms such as algae, mold, and fungi. Consequently, photocatalysis breaks down the molecules of virtually all organic compounds into their harmless basic components.
Normally, the heat that is produced by our bodies creates small drafts that carry microscopic particles including bacteria and viruses upwards towards the ceilings. Viruses such as SARS-CoV2, the novel human coronavirus that causes COVID-19 can continue floating in the air or spread through the ventilation A/C systems into other rooms and throughout the entire building. This problem is especially serious in hospitals and schools.
Consequently, if the Photocatalytic System is installed on the ceiling and around the ventilation systems airborne viruses and other pathogens will be trapped and destroyed.
The Photocatalytic System works silently and around the clock, when activated by
daylight or an artificial light. No toxic chemicals or allergens are released into the environment. All organic molecules are broken down into water (H2O) and Carbon Dioxide (CO2).
