What is Photo-catalysis?

Photocatalysis is a science of employing a catalyst that is utilized for speeding up chemical reactions that require or engages light. A photocatalyst is defined as a material that is capable of absorbing light, producing electron-hole pairs that enable chemical transformations of the reaction participants and regenerate its chemical composition after each cycle of such interactions.

But in Our project, we are mainly concerned with photocatalysis taking place on the surface of anatase( an ore of titanium dioxide).


 For people who are not from a science background, this can be explained as a series of oxidation that takes place on the surface of titanium dioxide.
