PHOTO CATALYST

Energy in the form of light Compund which initiate reaction/ make reaction faster

Principle of PHOTOCATALYST

Light SourceCatalyst

Reaction

HAPPEN!!!

Deodorization Anti-Bacteria Water treatment Dirtiness prevention

Advantegous of PHOTOCATALYST

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

Radical Oxygen

Radical

Hydroxyl

Valence Band

Conduction Band

Why PHOTOCATALYST ???

PHOTOCATALYST

is Energy SavingPhotocatalyst can be initiate by UV lamp and visible lamp

PHOTOCATALYST is

Relatively CheapPhotocatalyst raw material is relatively cheap

PHOTOCATALYST

is SustainableOnly need one time doping and never run out

PHOTOCATALYST is

Environmentally FriendlyPhotocatalyst convert hazardous organic contaminants and bacteria into harmless substance CO2 and H2O

PHOTOCATALYST

APPLICATION

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.

And many others PHOTOCATALYST APPLICATION

PHOTOCATALYST and NANOTECHNOLOGY will be

more advance time by the time.

LETS BE PART OF IT!!!
