Photocatalyst (Nano-TiO2)- SmartCoat
What is photocatalyst?What is photocatalyst?
Definition of "Photocatalyst"?
Photo = Light
Catalyst = a substance that causes or accelerates a Chemical reaction without itselfbeing affected.
How it works :How it works :
SMARTCOAT coated surface

bacteria and fungi by emitting oxygen radicals

Under the dark condition,water attached to the TiO2surface as water droplet
Just on a photo-irradiation, verythin water film is formed on the
surface of TiO2
Self cleaning Self cleaning Any stain on a TiO2 photocatalyst is removed.2 type self-cleaning mechanism exists
Stain is photodecomposed from theinterface of itself and TiO2 by radicalspecies generated with photo-irradiation
Thin water film is formed onto the TiO2surface by a photo-irradiation, andstain is slipped on this water film andremoved.

Why TiO2 is exclusive photocatalystWhy TiO2 is exclusive photocatalyst
Cheap- TiO2 is already widely is used for industrial field
Stable- TiO2 resists against acid or base
Safety -TiO2 is already using for food additive,cosmetics,and so on
Concentration of pollutantsConcentration of pollutants
Light is aggregate of particle called as photon.
Light intensity =number of photon.
Theoretically, one photon can occur one reaction.
Quantum efficiency (QE) is a quantity defined for a photocatalyst as the percentage of photons hitting the photoreactive surface that will produce an electron hole pair.
100% QE means that 1 photon generates 1 chemical reaction.
QE is under 100 %. total amount of photon > total amount of pollutant
