Other potential applications for photocatalysis plants could include train toilets, or around sewage and waste treatment facilities. |
In the area of photocatalysis, developing colloidal semiconductor systems capable of converting visible light to a useful form of energy has also been the center of attention. |
What we are proposing is the production of bioethanol from cellulosic waste using photocatalysis combined with the fermentation process in a single reactor. |
Nevertheless, the system does demonstrate for the first time the decontamination of a bacteria-containing air stream by photocatalysis at room temperature. |
The photocatalysis effect comes about because TiO 2 is a semiconductor that can absorb the high-energy component of sunlight. |
In photocatalysis, light energy from a UV-A light source excites an electron from the valence band of the catalyst to the conduction band. |
