Titanium Dioxide/ Titanium (IV) Oxide/ Titania - Coggle Diagram
Titanium Dioxide/ Titanium (IV) Oxide/ Titania
The most promising photocatalyst due to its appropriate electronic band structure, photo-stability, chemical inertness, and commercial availability.
Exists in form of powder, crystals, or thin films
Photocatalytic
Photosynthesize an example of Photocatalytic
Titanium dioxide is a semiconductor that, when coming in contact with light, produces electrons and electron holes
It then reacts with water and oxygen to create hydroxl radicals (•OH) and reactive oxygen allowing for the degradation and decomposition of harmful substances
This leads to a self-cleaning effect

Air Purification
Paint and Coating
Self-Cleaning Paint
Nano titanium dioxide is used in paint to exploit two of its excellent properties: Photocatalytic Activity and UV-activity
The combination of the photocatalytic effect, along with hydrophilic properties results in a paints' self-cleaning effect.
Nanofluid in HE
The presence of TiO2 nanoparticle can significantly enhance radiator's heat transfer rate in a manner dependent on nanoparticle quantity added to the base fluid.
