How PHOTOCATALYST works??

PHOTOCATALYST reaction
make radical hydroxyl (OH-) and
radical O2 with very strong

Radical hydroxyl (OH-) and radical O2 with very strong will
Destroy all and other organic contaminants into CO2 and H2O

Why PHOTOCATALYST ???
![Page 10: Photocatalyst Principle and Application](https://reader034.vdocument.in/reader034/viewer/2022050802/55a2092b1a28abc5788b48e6/html5/thumbnails/10.jpg)
PHOTOCATALYST
is Energy SavingPhotocatalyst can be initiate by UV lamp and visible lamp
![Page 11: Photocatalyst Principle and Application](https://reader034.vdocument.in/reader034/viewer/2022050802/55a2092b1a28abc5788b48e6/html5/thumbnails/11.jpg)
PHOTOCATALYST is
Relatively CheapPhotocatalyst raw material is relatively cheap

PHOTOCATALYST
is SustainableOnly need one time doping and never run out
![Page 13: Photocatalyst Principle and Application](https://reader034.vdocument.in/reader034/viewer/2022050802/55a2092b1a28abc5788b48e6/html5/thumbnails/13.jpg)
PHOTOCATALYST is
Environmentally FriendlyPhotocatalyst convert hazardous organic contaminants and bacteria into harmless substance CO2 and H2O
![Page 14: Photocatalyst Principle and Application](https://reader034.vdocument.in/reader034/viewer/2022050802/55a2092b1a28abc5788b48e6/html5/thumbnails/14.jpg)

SELFCLEANING GLASSDoping with nanoparticle photocatalyst made the glass hydrophobic and photocatalyst destroy the bacteria or other contaminants so glass always clean.

PHOTOCATALYTIC
WATER SPLITTINGPhotocatalyst convert H2O into H2 through oxidation process with the light irradiation. The example of efficient photocatalyst in the UV range is based on a sodium tantalite (NaTaO3) doped with La and loaded with a cocatalyst nickel oxide.

SODISSOLAR WATER DISINFECTIONDisinfection of water by supported photocatalysts. Photocatalyst reaction kill the bacteria inside the water with oxidation process.

CONVERTION of into
gaseous in the
presence of waterAt present, proposed reaction mechanisms usually suggest the creation of a highly reactive carbon radical from carbon monoxide and carbon dioxide which then reacts with the photogenerated protons to ultimately form methane.

STERILIZATION of Surgical Instruments And Removal Of Unwanted Fingerprints From Sensitive Electrical And Optical Components
Contaminants can be removed by UV light irradiation wtih the presence of photocatalyst

CRUDE OIL DECOMPOSITIONBy using photocatalysts and UV-A radiation from the sun, the hydrocarbons found in crude oil can be turned into H2O and CO2.

PHOTOCATALYST and NANOTECHNOLOGY will be
more advance time by the time.
