Photocatalytic Degradation of Methyl Orange with Titanium Dioxide Thin Films

The photocatalytic degradation of methyl orange under UV-ray with titanium dioxide thin films was investigated in this work. The effects of substrate, air bubbling flow, adding Fe3+ and H2O2 in methyl orange solution were examined. Fairly good coating conditions for the photocatalytic degradation of methyl orange in aqueoussolution were suggested.
