Titanium dioxide (TiO2) photocatalytic properties

Titanium dioxide (TiO2) photocatalytic properties

Titanium dioxide (TiO2) photocatalytic properties

(OP)
When TiO2 captures UV rays, it causes a photocatalytic reaction and oxidizes organic compounds present into water and carbon dioxide. Can someone help or point me in the right direction in tring to figure out how much CO2 and H2O is given off in this reaction? I am trying to figure how much CO2 & H2O is given off in a given time, per square foot (or sample area) of TiO2.

RE: Titanium dioxide (TiO2) photocatalytic properties

It depends on the composition of the compound

Check out this report:

I don't think you can calculate what you want to know. It needs to be experimentally determined because there are so many unknown factors involved. Quantum efficiency for photon conversion, particle size, diffusion rates, etc.
