Definitions
- the photocatalytic material is titanium dioxide, preferably anatase titanium dioxide crystals (TiO 2 ).
- TiO 2 anatase titanium dioxide crystals
- other semiconductor materials can be used for providing the advantages according to the present invention, such as TiO 2 , CdS, ZnO, WO 3 and combinations thereof, and compounds which increase the output of the transference of the charge separations, such as SnO 2 and RuO 2 and any combination thereof, which leads to an efficient charge separation and high quantum yield from the light employed.
- Fig. 2 shows a container with a reactor chamber for a system according to a second embodiment of the invention
