Hi,
I am currently working on titanium dioxide thin films which are growned on glass substrate. TiO2 has several peaks (101), (004), (200), (105), (211), (204), (116). What peak is mainly dominate photo-catalyst activity?
Please help in these case.
Thanking in advance for sincerely cooperation.
In general, the degradation of dyes depends on several parameters such as pH, catalyst concentration, substrate concentration and the presence of oxidants. Reaction temperature and the intensity of light also affect the degradation of dyes. Particle size, BET-surface area and different mineral forms of TiO2 also have influence on the degradation rate. TiO2 has a wide band gap (3.2 eV—anatase, 3.00 eV—rutile and 3.13 eV—brookite), which limits its absorption in the UV region of solar spectrum (Kuang et al. 2009; Khan et al. 2002; Atta et al. 2011). You will get more clear idea from the article given below:
