摘要：
Titanium oxide (TiO2) powders with equal specific surface area but with different crystalline phase (rutile and anatase) were modified with Fe using FeCl3 or Fe(acac)(3) with two modification techniques: metal cluster grafting (MCG) and chemisorption calcination cycle (CCC). Then, visible-light photocatalytic activity of the obtained powders was evaluated by the decomposition of gaseous 2-propanol (IPA). The modified powders possessed almost identical morphology and specific surface area. Visible light photocatalytic activity was increased remarkably by the Fe-modified rutile-phase TiO2 prepared using both techniques. The photocatalytic activity, action spectra, and the binding energy shift of oxygen suggest that these two techniques provide different mechanisms for visible light photocatalytic activity.
